Book excerpt: In this dissertation, we investigated ZnSe-based materials, which are interesting for a variety of potential applications in various devices. There was only limited information available in the literature about Zn1-xMnxSe material parameters like the electron effective mass and transport properties. In this work, we explored many new details about this interesting material using Fourier transform infrared spectroscopy and some other experimental techniques. The fundamental aspects related to lattice vibrations in mixed crystal alloys and reststrahlen band were also studied. In summary the following results have been obtained in this thesis: (A) Results from the series of chlorine-doped Zn1-xMnxSe samples: To extract information about the electron effective mass we performed roomtemperature plasma edge measurements on chlorine-doped n-type Zn1-xMnxSe epilayers. Via Drude-Lorentz-type multi-oscillator fits to our data, we extracted the optical electron effective mass (m*) in chlorine doped Zn1-xMnxSe:Cl samples for different Mn contents and free-electron concentrations. The free-electron concentration was determined using room-temperature van-der-Pauw Hall effect measurements. Our results indicate that: (A1) The electron effective mass in Zn1-xMnxSe is lower than that for ZnSe. A distinct reduction of the electron effective mass is observed upon Mn incorporation.
Book Synopsis High Magnetic Fields in Semiconductor Physics II by : Gottfried Landwehr

This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains contributions presented at the International Conference "The Application of High Magnetic Fields in Semiconductor Physics", which was held at the University of Wiirzburg from August 22 to 26, 1988. In the tradition of previous Wiirzburg meetings on the subject - the first conference was held in 1972 - only invited papers were presented orally. All 42 lecturers were asked to review their subject to some extent so that this book gives a good overview of the present state of the respective topic. A look at the contents shows that the subjects which have been treated at previous conferences have not lost their relevance. On the contrary, the application of high magnetic fields to semiconductors has grown substantially during the recent past. For the elucidation of the electronic band structure of semicon ductors high magnetic fields are still an indispensable tool. The investigation of two-dimensional electronic systems especially is frequently connected with the use of high magnetic fields. The reason for this is that a high B-field adds angular momentum quantization to the boundary quantization present in het erostructures and superlattices. A glance at the contributions shows that the majority deal with 2D properties. Special emphasis was on the integral and fractional quantum Hall effect. Very recent results related to the observation of a fraction with an even denbminator were presented. It became obvious that the polarization of the different fractional Landau levels is more complicated than originally anticipated.

Book Synopsis Semiconductor Nanostructures by : Dieter Bimberg

Available in PDF, EPUB and Kindle. Book excerpt: Reducing the size of a coherently grown semiconductor cluster in all three directions of space to a value below the de Broglie wavelength of a charge carrier leads to complete quantization of the energy levels, density of states, etc. Such “quantum dots” are more similar to giant atoms in a dielectric cage than to classical solids or semiconductors showing a dispersion of energy as a function of wavevector. Their electronic and optical properties depend strongly on their size and shape, i.e. on their geometry. By designing the geometry by controlling the growth of QDs, absolutely novel possibilities for material design leading to novel devices are opened. This multiauthor book written by world-wide recognized leaders of their particular fields and edited by the recipient of the Max-Born Award and Medal 2006 Professor Dieter Bimberg reports on the state of the art of the growing of quantum dots, the theory of self-organised growth, the theory of electronic and excitonic states, optical properties and transport in a variety of materials. It covers the subject from the early work beginning of the 1990s up to 2006. The topics addressed in the book are the focus of research in all leading semiconductor and optoelectronic device laboratories of the world.

Book Synopsis Optical Characterization of Epitaxial Semiconductor Layers by : Günther Bauer
Download or read book Optical Characterization of Epitaxial Semiconductor Layers written by Günther Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The characterization of epitaxial layers and their surfaces has benefitted a lot from the enormous progress of optical analysis techniques during the last decade. In particular, the dramatic improvement of the structural quality of semiconductor epilayers and heterostructures results to a great deal from the level of sophistication achieved with such analysis techniques. First of all, optical techniques are nondestructive and their sensitivity has been improved to such an extent that nowadays the epilayer analysis can be performed on layers with thicknesses on the atomic scale. Furthermore, the spatial and temporal resolution have been pushed to such limits that real time observation of surface processes during epitaxial growth is possible with techniques like reflectance difference spectroscopy. Of course, optical spectroscopies complement techniques based on the inter action of electrons with matter, but whereas the latter usually require high or ultrahigh vacuum conditions, the former ones can be applied in different environments as well. This advantage could turn out extremely important for a rather technological point of view, i.e. for the surveillance of modern semiconductor processes. Despite the large potential of techniques based on the interaction of electromagnetic waves with surfaces and epilayers, optical techniques are apparently moving only slowly into this area of technology. One reason for this might be that some prejudices still exist regarding their sensitivity.

Book Synopsis Narrow-gap II-VI Compounds for Optoelectronic and Electromagnetic Applications by : Peter Capper
Download or read book Narrow-gap II-VI Compounds for Optoelectronic and Electromagnetic Applications written by Peter Capper and published by Springer Science & Business Media. This book was released on 1997-10-31 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of narrow-gap II-VI materials is dominated by lhe compound mercury cadmium telluride, MCT or Hg1_ .. Cd .. Te. By varying the x value, material can be made to cover all the important infrared (lR) ranges of interest. It is probably true to say that MCT is the third most studied semiconductor after silicon and gallium arsenide. As current epitaxial layers of MCT are mainly grown on bulk CdTe family substrates these materials are included in this book, although strictly, of course, they are not 'narrow-gap'. This book is intended for readers who are either new to the field or are experienced workers in the field who need a comprehensive and up to date view of this rapidly expanding area. To satisfy the needs of the frrst group each chapter discusses the principles underlying each topic and some of the historical background before bringing the reader the most recent information available. For those currently in the field the book can be used as a collection of useful data, as a guide to the literature and as an overview of topics covering the wide range of work areas.
