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. WebSep 7, 2024 · Fitting to the data, we estimate an effective mass of valence-band holes (18.8 m0) and an ultrafast self-trapping time of holes (0.045 fs). This indicates that minority-hole transport in β−Ga2O3 can only arise through tunnel ionization of STHs under strong fields. Received 31 October 2024 Revised 21 July 2024 Accepted 11 August 2024
