i] is the average deformation potential accounting for coupling between the system and the mechanical stress applied; [E.
It may be argued, therefore, that the composition dependence of the effective deformation potential of coupling between semi-IPNs and external mechanical stress is similar to that for [T.
He includes structural properties, thermal properties, elastic properties, lattice dynamic properties, collective effects and response characteristics, energy-band structures and gaps, energy- band effective masses, deformation potentials, electron affinity and Schottky barrier height, various optical properties and carrier transport systems.
