The data and plots shown in this Appendix are extracted from a number of sources. A list of useful sources is given below. Note that impact ionization coefficient and Auger coefficients of many materials are not known exactly.

• S. Adachi, J. Appl. Phys., 58, R1 (1985).

• H.C. Casey, Jr. and M.B. Panish, Heterostructure Lasers, Part A, “Fundamental Principles;” Part B, “Materials and Operating Characteristics,” Academic Press, N.Y. (1978).

• Landolt-Bornstein, Numerical Data and Functional Relationship in Science and Technology, Vol. 22, Eds. O. Madelung, M. Schulz, and H. Weiss, Springer-Verlog, N.Y. (1987). Other volumes in this series are also very useful.

• S.M. Sze, Physics of Semiconductor Devices, Wiley, N.Y. (1981). This is an excellent source of a variety of useful information on semiconductors.

• “World Wide Web;” A huge collection of data can be found on the Web. Several professors and industrial scientists have placed very useful information on their websites.
