First - Principles Cluster Investigation of Nuclear Quadrupole Interactions of ^69,71Ga and ^17N Nuclei in Gallium Nitride
Abstract
As part of our investigations of electronic structure and properties of GaN, in particular the recent study of trapped muonium hyperfine interactions [1] in this system, we have been investigating the nuclear quadrupole interactions of ^69,71Ga and ^17N Nuclei in pure GaN using the Hartree-Fock Cluster procedure together with incorporation of many-body effects. Our results will be presented and compared with both available experimental quadrupole coupling constants [2] and earlier theoretical results [2] by the point charge model and band-structure methods.
