Abstract This work presents a program, based on the Van de Walle-Martin model solid theory, able to compute the most important physical quantities of any In_(1-x)Ga_x As_y P_(1-y)quaternary epitaxially strained growth on any In_(1-z)Ga_z As_w P^(1-w), hypothetical substrate. The adopted interface-band alignment procedure is extensively described. The effect of strain on several examples of ideal heterostructures characterized by abrupt interfaces is discussed in detail. Furthermore, the probl... Title of program: BANDSTRAIN Catalogue Id: ADCM_v1_0 Nature of problem Biaxial compression or tension induced by the presence of a mismatch between the lattice parameter of the substrate and the growth epitaxial layers implies a deformation of the bands profiles of electrons, heavy and light holes along the growth axis [2] causing the removal of the degeneration of the heavy and light holes bands. Due to the technological difficulties in executing instantaneous group V switches even non intentionally strained III-V heterostructures present strained layer at the int ...
