Nature of exciton transitions in hexagonal boron nitride

Li, J.; Cao, X. K.; Hoffman, Timothy B.; Edgar, James H.; Lin, J. Y.; Jiang, H. X.

In contrast to other III-nitride semiconductors GaN and AlN, the intrinsic (or free) exciton transition in hexagonal boron nitride (h-BN) consists of rather complex fine spectral features (resolved into six sharp emission ...
Raman characterization and stress analysis of AlN grown on SiC by sublimation

Liu, L.; Liu, B.; Edgar, James H. (2010-07-29)

The stress distribution in bulk AlN crystals seeded on 6H–SiC was theoretically modeled and also determined experimentally from Raman peak positions. The full width at half maximum of the AlN Raman peaks showed the crystal ...
