Interplay of Strain and Short Range Ordering at Nitride Heterointerfaces

Abstract

This report presents research conducted by Dr. Andrew C. Lang (Code 6366) during her Jerome and Isabella Karle Distinguished Scholar Fellowship from September 27th, 2021 - September 26th, 2022. It describes research into the interplay of strain and short range ordering at nitride heterointerfaces. The two material systems under examination here include high Sc-fraction ScAlN and cubic-boron nitride. Both of these epitaxial systems represent the state of the art in nitride synthesis, and as a result there is little known about the complex interplay of local structural defect, strain, phase/growth relationships resulting from epitaxial growth. This work aids in identifying the path towards future nitride heterostructure development and opens the door for future detailed studies on the relationship on local compositional and chemical ordering in device based on nitride heterostructures.
