Download or read book Research in Purification and Single Growth of Ii vi Compounds written by Richard H. Fahrig and published by . This book was released on 1967 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: A process for the purification of cadmium metal by multiple treatment steps is described. Impurities in cadmium, as determined by emission spectrographic, mass spectrographic, and atomic absorption are given in tabular form. The preparation of various pure semiconductor materials of the Group II-VI compound type is discussed and tables of analytical data for each are included. The level of impurity concentration in synthesized cadmium sulfide was significantly lowered. Less than 1 part per million (atomic) total impurities was found by the mass spectrograph in two batches of CdS. The growth of crystals of pure II-VI compounds and mixtures of compounds from the melt is reported. Included are data concerning doping of melt grown crystals with various elemental dopants, and, in the case of some compound semiconductors, the maximum doping levels possible by this method. (Author).

Book excerpt: Using defect thermodynamics, we discuss physical factors that affect doping limits in semiconductors. The dependencies of the defect formation enthalpy on the atomic chemical potentials and on the electron Fermi energy are demonstrated. These dependencies, in particular on the Fermi energy, lead to spontaneous formation of charge-compensating defects that can limit doping. Experimental data compiled for III-V, II-VI, and I-III-VI2 compounds support this view and further provide insight into the connections among different host materials. We argue that what matters is not the magnitude of the band gap that determines the dopability of a material, but rather, the relative position of the conduction-band minimum (in the case of n-doping) and the valence-band maximum (in the case of p-doping) with respect to vacuum.

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.

Book excerpt: The amphoteric native defect model is applied to the understanding of the variations in the dopant activation efficiency in II-VI compounds. It is shown that the location of the common energy reference, the Fermi level stabilization energy, relative to the band edges can be used to determine the doping induced reduction of the formation energy and the enhancement of the concentration of compensating native defects. The model is applied to the most extensively studied compound semiconductors as well as to ternary and quaternary alloys. The effects of the compound ionicity on the dopant activation are briefly discussed.
