Abstract:
1. A method comprising: growing a compound semiconductor layer on a substrate with a first thickness such that the compound semiconductor layer is in a metastable state, wherein the metastable state is obtained by setting the first thickness to exceed a critical thickness of an elemental concentration associated with a first element included in the compound semiconductor; determining an amount by which the elemental concentration of the first element exceeds a base concentration of the first element corresponding to a stable state of the compound semiconductor layer at the first thickness; determining a concentration of a strain-compensating atomic species that is configured to strain compensate, at the first thickness, the amount by which the elemental concentration of the first element exceeds the base concentration of the first element; and adding the strain-compensating atomic species to the compound semiconductor layer during growth of the compound semiconductor layer, at the determined concentration to maintain the compound semiconductor layer in a strained state at the first thickness.
