This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The advancement of semiconductor technology has popularized the low power, economical and small form-factor solid state devices, such as those highly integrated and interconnected as the fundamental infrastructure for the internet of things (IoT). Due to its CMOS-compatibility and electrical interface, the biosensor utilizing field effect transistor (FET) as transducer has become the perfect candidate to interface directly with the chemical and biological properties of the physical world. Especially, nanowire (NW) FET biosensor has received great attention as a highly sensitive biosensing platform, benefiting from its increased surface-to-volume ratio. In this work, several challenges and key aspects of existing NW FET biosensor were studied, and solutions were proposed to address these problems. For example, the hydrolytic stability of the surface sensing element was evaluated and improved by a hydrolysis process, which led to a significant increase in the overall biosensor performance. Another challenge is the noise in the electric potential of the sensing solutions. A secondary reference electrode was introduced in the biosensing system, and its potential was used to subtract the noise from the measured sensor output. Compared to a reference FET, this approach greatly reduced the system complexity and requirement, yet still improved the limit of detection (LOD) by 50 – 70%. This work also involved careful investigation into the analyte sensitivity, which can be considerably affected by the charge buffering effect from the surface hydroxyl groups. Analytical studies and numerical simulations were carried out, revealing that both low pH sensitivity and large analyte buffer capacity are required to achieve a reasonable analyte sensitivity. The most significant portion of this work was the experimental demonstration of the digital biosensing concept with single serpentine NW FET biosensor. The majority of existing FET biosensors utilized the device as an analog transducer, which measures the captured analyte density to generate an output, and suffers from various noise factors, especially the nonspecific changes of the sensing solutions than cannot be reduced by averaging. Digital biosensor no longer depends on the amplitude of the sensor output and is therefore better immune from these noise factors. Instead, the individual binding event of single analyte is counted and analyzed statistically to determine the analyte concentration. The single serpentine NW FET is the ideal device design to achieve digital biosensing. It maintains the low noise level with the equivalently long channel, yet achieves a small footprint enough for binding of only a single analyte. The binding of analyte to multiple segments of the NW results in both higher sensitivity and binding avidity. The small footprint also enables high integration density of the individual digital biosensors into an array format, which is a responsive, highly sensitive, and cost-effective future biosensing platform.

This book was released on 2011 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quasi one-dimensional (1-D) field-effect transistors (FET), such as Si nanowire FETs (Si NW-FETs), have shown promise for more aggressive channel length scaling, better electrostatic gate control, higher integration densities and low-power applications. At the same time, an accurate bench-marking of their performance remains a challenging task due to difficulties in definition of the exact channel length, gate capacitance and transconductance. In 1-D Si FETs, one also often observes a significant degradation of their mobility and on/off ratio. The goal of this study is to implement the idea of the FET performance enhancement while simultaneously performing a more rigorous data extraction. To achieve these goals, we fabricated dual-gate undoped Si NW-FETs with various NW diameters The Si NWs are grown by Au-catalyzed vapor-transport For our top-gate NW-FET, the subthreshold swing was determined to be 85-90 mV/decade, whereas the best subthreshold swings for Si NW-FETs until now were ~135-140 mV/decade. We achieved a ON/OFF current ratio of 10 7 due to improved electrostatic control and electron transport conditions inside the channel. This is on the higher end of any ON/OFF ratios thus far reported for NW FETs The hole mobility in our NW-FETs was around 250.400 cm[superscript 2] /Vs, according to different extraction procedures. In our mobility calculations we included the NW silicidation effect, which reduces the effective channel length. We calculated the top gate capacitance using Technology Computer Aided Design (TCAD) Sentaurus simulator, which gives more accurate value of capacitance of the NW over any analytical formulas. Thus we fabricate and rigorously study Si NW.s intrinsic properties which are very important for digital logic circuit application. In the second part of the study, we carried out simulation of Si NW FET devices to shed light on the carrier transport behavior that also explains experimental data.

Book Synopsis Fundamentals of III-V Semiconductor MOSFETs by : Serge Oktyabrsky
Download or read book Fundamentals of III-V Semiconductor MOSFETs written by Serge Oktyabrsky and published by Springer Science & Business Media. This book was released on 2010-03-16 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of III-V Semiconductor MOSFETs presents the fundamentals and current status of research of compound semiconductor metal-oxide-semiconductor field-effect transistors (MOSFETs) that are envisioned as a future replacement of silicon in digital circuits. The material covered begins with a review of specific properties of III-V semiconductors and available technologies making them attractive to MOSFET technology, such as band-engineered heterostructures, effect of strain, nanoscale control during epitaxial growth. Due to the lack of thermodynamically stable native oxides on III-V's (such as SiO2 on Si), high-k oxides are the natural choice of dielectrics for III-V MOSFETs. The key challenge of the III-V MOSFET technology is a high-quality, thermodynamically stable gate dielectric that passivates the interface states, similar to SiO2 on Si. Several chapters give a detailed description of materials science and electronic behavior of various dielectrics and related interfaces, as well as physics of fabricated devices and MOSFET fabrication technologies. Topics also include recent progress and understanding of various materials systems; specific issues for electrical measurement of gate stacks and FETs with low and wide bandgap channels and high interface trap density; possible paths of integration of different semiconductor materials on Si platform.

Download or read book Piezotronics and Piezo-Phototronics written by Zhong Lin Wang and published by Springer Science & Business Media. This book was released on 2013-01-11 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental principle of piezotronics and piezo-phototronics were introduced by Wang in 2007 and 2010, respectively. Due to the polarization of ions in a crystal that has non-central symmetry in materials, such as the wurtzite structured ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a stress. Owing to the simultaneous possession of piezoelectricity and semiconductor properties, the piezopotential created in the crystal has a strong effect on the carrier transport at the interface/junction. Piezotronics is for devices fabricated using the piezopotential as a “gate” voltage to control charge carrier transport at a contact or junction. The piezo-phototronic effect uses the piezopotential to control the carrier generation, transport, separation and/or recombination for improving the performance of optoelectronic devices, such as photon detector, solar cell and LED. The functionality offered by piezotroics and piezo-phototronics are complimentary to CMOS technology. There is an effective integration of piezotronic and piezo-phototronic devices with silicon based CMOS technology. Unique applications can be found in areas such as human-computer interfacing, sensing and actuating in nanorobotics, smart and personalized electronic signatures, smart MEMS/NEMS, nanorobotics and energy sciences. This book introduces the fundamentals of piezotronics and piezo-phototronics and advanced applications. It gives guidance to researchers, engineers and graduate students.
