Light point defect
WebGaN Schottky barrier ultraviolet photodetectors with unintentionally doped GaN and lightly Si-doped n−-GaN absorption layers were successfully fabricated, respectively. The high-quality GaN films on the Si substrate both have a fairly low dislocation density and point defect concentration. More importantly, the effect of Si doping on the performance of the … WebPoint defect definition, an imperfection in a crystal's lattice structure, either a missing atom or ion creating a vacancy in the lattice or an extra atom or ion between two normal lattice …
