Abstract

Directly grown nanocrystalline h-BN thin films on 4H-SiC substrates exhibit strong second-harmonic generation and low cross-plane thermal conductivity, attributed to twisted nano-domain edges and random in-plane orientations; TDDFT calculations support strong even-order optical nonlinearity.
