This book was released on 1971 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using a metalorganic-hydride process for the formation of epitaxial layers of Ga(1-x)InxAs alloy semiconductors on n-type GaAs and InAs single-crystal substrates has been investigated. Conditions have been established for the preparation of single-crystal layers with bandgap energies between 0.7 and 0.8 eV. The investigation has been based on a chemical vapor deposition process employing metalorganics such as trimethylgallium and triethylindium and gaseous hydrides such as arsine for growth of the alloys on the above substrates and on sapphire (Al2O3), the latter to facilitate evaluation of the alloy films. The feasibility of growth of alloys in a range of compositions has been clearly demonstrated. Carrier concentrations the order of 10 to the 16th power cu cm or below have been obtained, and room temperature mobilities as high as nearly 10,000 sq cm/V-sec on (0001) Al2O3 and over 4000 sq cm/v-sec on (111) GaAs ('A' face) have been achieved. Experimentally determined optical bandgap energies and alloy compositions for the Ga1-xInxAs films indicate a smooth continuous variation of bandgap with the mole fraction of either cation. A bandgap energy of 0.7 eV results for a film containing 0.40 - 0.45 mole fraction of Ga. (Author).

Book Synopsis Nanomagnetism and Spintronics by : Fumihiro Matsukura
Download or read book Nanomagnetism and Spintronics written by Fumihiro Matsukura and published by Elsevier Inc. Chapters. This book was released on 2013-10-07 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: III–V compound semiconductors such as GaAs and InAs alloyed with Mn exhibit ferromagnetism. The magnetic, electrical, and optical properties of ferromagnetic III–V semiconductors are first compiled along with the way to prepare the epitaxial films and the effect of postgrowth annealing. Theories available to explain the magnetism in these alloys are then presented. Because the ferromagnetic semiconductors are compatible with epitaxial III–V heterostructures, a number of device structures have been examined and shown to reveal a wide variety of phenomena that either cannot be realized or are very difficult to observe in ferromagnetic metal structures. The unique properties revealed by ferromagnetic semiconductor structures, ranging from reversible electric field control of ferromagnetic phase transition to generating velocity versus current-density curves of current-induced domain wall motion, are then reviewed. The prospect of realizing high-transition temperature is discussed in the last section.

Book Synopsis Copper Zinc Tin Sulfide-Based Thin-Film Solar Cells by : Kentaro Ito
Download or read book Copper Zinc Tin Sulfide-Based Thin-Film Solar Cells written by Kentaro Ito and published by John Wiley & Sons. This book was released on 2015-02-23 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with an overview and historical background of Copper Zinc Tin Sulphide (CZTS) technology, subsequent chapters cover properties of CZTS thin films, different preparation methods of CZTS thin films, a comparative study of CZTS and CIGS solar cell, computational approach, and future applications of CZTS thin film solar modules to both ground-mount and rooftop installation. The semiconducting compound (CZTS) is made up earth-abundant, low-cost and non-toxic elements, which make it an ideal candidate to replace Cu(In,Ga)Se2 (CIGS) and CdTe solar cells which face material scarcity and toxicity issues. The device performance of CZTS-based thin film solar cells has been steadily improving over the past 20 years, and they have now reached near commercial efficiency levels (10%). These achievements prove that CZTS-based solar cells have the potential to be used for large-scale deployment of photovoltaics. With contributions from leading researchers from academia and industry, many of these authors have contributed to the improvement of its efficiency, and have rich experience in preparing a variety of semiconducting thin films for solar cells.
