Structural optimization of lattice-matched Sc0.14Al0.86N/GaN superlattices for photonic applications
Rajendra Kumar, Govardan Gopakumar, Zain Ul Abdin +2
ScxAl1-xN is an emerging III-nitride material known for its high piezoelectric coefficient and ferroelectric properties. Integration of wide-bandgap ScxAl1-xN with GaN is particula…

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 layers on (0001) GaN to be x = 0.14+/-0.01. 1…
