Abstract : In connection with a theoretical study of surface transport in semiconductors, numerical evaluation of the final mobility formula was required. The mobility formula has the form of an integral of a transcendental function of an integral. Evaluation was required for a finite number of values of two parameters, one being the lower limit of the outer integral, the other occurring in the integrand of the inner integral. After removal of a singularity in the inner integral, both integrals were evaluated by Gaussian quadratures. The evaluation was done on the IBM 704 computer using the FORTRAN program given in this report. (Author)
