WebAbstract. Combining the self-consistent-field molecular-orbital results for the wave functions and energies of F− 2 and Cl− 2 with a classical calculation of the lattice distortion and polarization energies, we have obtained the ground- and excited-state potential curves of the V K center in several of the alkali halides. WebThe small radius hole polarons (self-trapped holes (STH) known also as the V k centers) are very common color centers observed in numerous alkali halides and alkaline-earth halides. Their mobility controls the rate of secondary reactions between electron and hole defects and thus radiation stability/sensitivity of materials. We have analysed here the correlation …
WebMar 10, 2016 · We conclude that self-trapped hole formation near the Schottky diode lowers the effective Schottky barrier in reverse bias, producing photoconductive gain. Ascribing photoconductive gain to an inherent property like self-trapping of holes can explain the operation of a variety of β-Ga 2 O 3 photodetectors. Authors:
