Low concentration detection, specific biomolecule detection, and point-of-care use are appealing characteristics for biosensors because of the possibility of early detection and quick results of specific biomolecules. Furthermore, inexpensive biosensors are appealing so that they are accessible to the general population. The biosensors in this study have the potential to satisfy these characteristics. In this study graphene field-effect transistors (G-FET) were fabricated. Graphene was grown using chemical vapor deposition (CVD) and transferred to a silicon/silicon oxide substrate. The CVD method is the most scalable and cost-effective method of producing graphene for devices. Standard photolithography was used to pattern and then deposit metal electrodes. Two separate experiments were conducted; one using electrostatic attraction to bind protein to the active area of the G-FET to detect the protein poly-L-lysine (PLL) and one using an aptamer modified G-FET to selectively detect the protein thrombin. Analyte was delivered using a homebuilt, pressure driven, microfluidic, mass flow system. Both experiments showed a detection of the protein. The PLL experiment showed a clear change in the effective gate voltage of the G-FET. The thrombin experiment showed a change in the effective gate voltage that varied with differing concentrations of thrombin present. Furthermore, in the thrombin experiment by changing from a thrombin solution back to buffer the effective gate voltage was brought back to its original value. A competing protein was introduced and gave a signal comparable to the signal of a 10 times smaller concentration of thrombin. All of this shows that CVD grown graphene in a FET biosensor can be used for protein detection. Furthermore, the specific detection of thrombin suggests that aptamer modified G-FETs with CVD grown graphene can be used as a protein specific biosensor.

Book excerpt: The thesis by Mercè Pacios exploits properties of carbon nanotubes to design novel nanodevices. The prominent electrochemical properties of carbon nanotubes are used to design diverse electrode configurations. In combination with the chemical properties and (bio)functionalization versatility, these materials prove to be very appropriate for the development of electrochemical biosensors. Furthermore, this work also evaluates the semiconductor character of carbon nanotubes (CNT) for sensor technology by using a field effect transistor configuration (FET). The CNT-FET device has been optimized for operating in liquid environments. These electrochemical and electronic CNT devices are highly promising for biomolecule sensing and for the monitoring of biological processes, which can in the future lead to applications for rapid and simple diagnostics in fields such as biotechnology, clinical and environmental research.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes initial efforts, as part of the new Strategic Technology Institute (STI) on carbon electronics, to model and simulate the performance of graphene field-effect transistors (FETs) using macroscopic descriptions that are classical for semiconductor devices. It is argued that the underlying physics that differentiates these devices from their normal semiconductor-based counterparts is most clearly revealed by non-computer-intensive descriptions that allow the designer to compare their behaviour with that of their well-studied semiconductor counterparts. Because it admits a reasonable description of both the lateral and vertical field and transport functionality of the FET structure, the gradual-channel approximation is key to this approach.

Infectious diseases continue to be a challenge that necessitates increased precision in detection and integration to achieve accurate diagnosis at the point of care (PoC). Field-effect transistors (FETs) have been investigated widely as biosensors for pathogen detection, with advantages such as label-free and real-time detection capabilities. These biosensors have: a high level of sensitivity, a remarkable capacity for miniaturization, a molecular minimum limit of detection (LoD), and seamless integration with semiconductor technology In this title, we have invited expert scientific researchers to share their experience in this field. This book focuses on the application and possibility of FETs as biosensors, for rapid and real time detection of pathogens that affect human life. The lack of commercially available efficient devices that can be deployed for this task resulted in the recent global spread of the SARS-CoV-19 virus. The book is an attempt to keep interested parties up to date. Aimed at scientists and engineers (researchers, academics, and postgraduate students) who are interested in developing and using BioFET based sensors, the information in this book is crucial to help prevent future outbreaks of pathogens which bring with them significant impacts on human health and wellbeing.

This book was released on 2017-10-29 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses analytical approaches and modeling of the breakdown voltage (BV) effects on graphene-based transistors. It presents semi-analytical models for lateral electric field, length of velocity saturation region (LVSR), ionization coefficient (α), and breakdown voltage (BV) of single and double-gate graphene nanoribbon field effect transistors (GNRFETs). The application of Gauss’s law at drain and source regions is employed in order to derive surface potential and lateral electric field equations. LVSR is then calculated as a solution of surface potential at saturation condition. The ionization coefficient is modelled and calculated by deriving equations for probability of collisions in ballistic and drift modes based on the lucky drift theory of ionization. The threshold energy of ionization is computed using simulation and an empirical equation is derived semi-analytically. Lastly avalanche breakdown condition is employed to calculate the lateral BV. On the basis of this, simple analytical and semi-analytical models are proposed for the LVSR and BV, which could be used in the design and optimization of semiconductor devices and sensors. The proposed equations are used to examine BV at different channel lengths, supply voltages, oxide thickness, GNR widths, and gate voltages. Simulation results show that the operating voltage of FETs could be as low as 0.25 V in order to prevent breakdown. However, after optimization, it can go as high as 1.5 V. This work is useful for researchers working in the area of graphene nanoribbon-based transistors.

This book was released on 2019-12-06 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: With recent advancements in electronics, specifically nanoscale devices, new technologies are being implemented to improve the properties of automated systems. However, conventional materials are failing due to limited mobility, high leakage currents, and power dissipation. To mitigate these challenges, alternative resources are required to advance electronics further into the nanoscale domain. Carbon nanotube field-effect transistors are a potential solution yet lack the information and research to be properly utilized. Major Applications of Carbon Nanotube Field-Effect Transistors (CNTFET) is a collection of innovative research on the methods and applications of converting semiconductor devices from micron technology to nanotechnology. The book provides readers with an updated status on existing CNTs, CNTFETs, and their applications and examines practical applications to minimize short channel effects and power dissipation in nanoscale devices and circuits. While highlighting topics including interconnects, digital circuits, and single-wall CNTs, this book is ideally designed for electrical engineers, electronics engineers, students, researchers, academicians, industry professionals, and practitioners working in nanoscience, nanotechnology, applied physics, and electrical and electronics engineering.
