Electronic band structure of highly mismatched GaN1?xSbx alloys in a broad composition range (2015)
Journal Article
Segercrantz, N., Yu, K., Ting, M., Sarney, W., Svensson, S., Novikov, S., …Walukiewicz, W. (in press). Electronic band structure of highly mismatched GaN1−xSbx alloys in a broad composition range. Applied Physics Letters, 107(14), Article 142104. https://doi.org/10.1063/1.4932592

In this letter, we study the optical properties of GaN1?xSbx thin films. Films with an Sb fraction up to 42% were synthesized by alternating GaN-GaSb layers at a constant temperature of 325 ?C. The measured optical absorption data of the films are in... Read More about Electronic band structure of highly mismatched GaN1?xSbx alloys in a broad composition range.

Anharmonic phonon decay in cubic GaN (2015)
Journal Article
Cuscó, R., Domènech-Amador, N., Novikov, S. V., Foxon, C. T., & Artús, L. (2015). Anharmonic phonon decay in cubic GaN. Physical Review B, 92(7), Article 075206. https://doi.org/10.1103/PhysRevB.92.075206

We present a Raman scattering study of optical phonons in zincblende (cubic) GaN for temperatures ranging from 80 to 750 K. The experiments were performed on high quality, cubic GaN films grown by molecular beamepitaxy on GaAs (001) substrates. The o... Read More about Anharmonic phonon decay in cubic GaN.
