APPENDIX C
COMPUTER PROGRAM
This appendix contains the FORTRAN computer program used to
generate values of conductivity and Hall effective mass, conductivity and Hal] mobility, and Hall factor as functions of temperature and acceptor impurity density in silicon. Besides the main program, two subroutines are also listed. The first of these, DENSTY, calculates the hole density by iterating the Fermi energy level in the charge balance equation as explained in Chapter IV; the second, INTBND, computes the coefficients (functions L jand'Ti of equations (3.7) through (3.9)) used in the calculations of acoustic phonon scattering based on the work of Bir et a] [43].
