Numerical Simulation of the Growth of HgCdTe Layers by Isothermal Vapor Phase Epitaxy

Abstract

We study the covariant entropy bound in the context of gravitational collapse. First, we discuss critically the heuristic arguments advanced by Bousso. Then we solve the problem through an exact model: a Tolman-Bondi dust shell collapsing into a Schwarzschild black hole. After the collapse, a new black hole with a larger mass is formed. The horizon, L, of the old black hole then terminates at the singularity. We show that the entropy crossing L does not exceed a quarter of the area of the old horizon. Therefore, the covariant entropy bound is satisfied in this process.

Isothermal vapour-phase epitaxy of mercury-cadmium telluride (Hg,Cd)Te

“…It was assumed in all the calculations that the rate of the epitaxial growth is determined only by the diffusion transport of tellurium (Equation 14). The numerical results agree with our previous results and, as can be seen, also with the experiments; they do not completely agree with the results presented in [87].…”

“…To calculate the velocity of the epitaxial layer growth Grove's theory of thermal oxidation shall be used [80,87]. There are three different fluxes of the particles (Fig.…”
