Pinpointing Lattice-Matched Conditions for Wurtzite ScxAl1-xN/GaN Heterostructures with X-Ray Reciprocal Space Analysis

Rajendra Kumar, Govardan Gopakumar, Zain Ul Abdin +2

Using comprehensive x-ray reciprocal space mapping, we establish the precise lattice-matching composition for wurtzite $S{c}_{x}A{l}_{1-x}N$ layers on (0001) GaN to be x = 0.14+/-0.01. 1…
