Boundary conditions in theory of photothermal processes

Abstract

The general boundary conditions for the thermal diffusion equation are obtained. It is shown that in the general case of a nonstationary photothermal process these boundary conditions must include both the surface thermal conductivity and surface thermal capacity. One more parameter, the surface capacity thermal impedance, appears in the boundary conditions when the photothermal process is the thermal wave propagation.

Boundary Conditions for Thermoelectric Cooling in p–n Junction

“…The coefficients N s , P s , and K s depend upon the concentrations n and p. Since we investigate the case of a linear approximation, then these parameters we take at an equilibrium temperature T 0 and at equilibrium concentrations, n n, p 0 and p n, p 0 . Comparison of the value of K s with the obtained earlier boundary conditions [12,27] allows one to conclude that K s is the surface thermal conductivity [28].…”
