Read shockley equation
The energy of a low-angle boundary is dependent on the degree of misorientation between the neighbouring grains up to the transition to high-angle status. In the case of simple tilt boundaries the energy of a boundary made up of dislocations with Burgers vector b and spacing h is predicted by the Read–Shockley equation: where: WebApr 10, 2024 · In this Letter, the trap inhomogeneity within β-Ga 2 O 3 is correlated with the conversion of Shockley–Read–Hall (SRH) recombination in NiO/β-Ga 2 O 3 p + –n heterojunction diodes. For the virgin epi-wafer, both near-surface traps E2 (E C-0.82 eV) and E3 (E C-1.11 eV) and bulk E2 * traps (E C-0.76 eV) are identified by a transient capacitance …
