Abstract

Abstract : In article number 2100009, the ab initio calculations by Cheol Seong Hwang, Jung‐Hae Choi, and co‐workers show that wurtzite‐type AlN can have a suitable range of ferroelectric switching barrier ( E a) and spontaneous polarization ( P s) by forming superlattice structures with ScN. The E a is dominated by the local structure instability, while the P s is significantly affected by the structural parameters and the Born effective charge.
