Polarized Photoluminescence From Nonpolar (11-20) (Ga,In)N Multi-Quantum-Wells

T. Gühne, Z. Bougrioua, M. Nemoz, R. Chmielowski, Thierry Bretagnon, Bernard Gil, M. Leroux

Nonpolar (11-20) (Ga,In)N multi-quantum wells have been studied by polarized, temperature dependent photoluminescence (PL). A non monotonic temperature dependence of the difference in PL peak energies recorded for E parallel to c or E perpendicular to c, and of the polarization ratio is observed.…

Development of Time-resolved UV Micro-Raman Spectroscopy to measure temperature in AlGaN/GaN HEMTs

Ophélie Lancry, Emmanuelle Pichonat, Julien Réhault, Myriam Moreau, Raphaël Aubry, Christophe Gaquière

We report on the development of Time-resolved Ultraviolet Micro-Raman Scattering to measure transient self-heating effects in semiconductor devices. Temperature measurements are performed on AlGaN/GaN High-electron-mobility transistors (HEMTs) grown on SiC substrate. Ultraviolet excitation probes…

Potentiality of commercial metamorphic HEMT at cryogenic temperature and low voltage operation

Albert M.D. Noudeviwa, Yannick Roelens, Francois Danneville, Aurélien Olivier, Nicolas Wichmann, Nicolas Waldhoff, Sylvie Lepilliet, Gilles Dambrine, L. Desplanque, X. Wallart, Joseph Bellaiche, Derek Smith, Hassan Maher, S. Bollaert

We present in this paper, a study of Dc, RF and Noise characteristics of an industrial metamorphic HEMT (High Electron Mobility Transistor) operating under low voltage at cryogenic temperature. The results at 300K are compared with the obtained results at cryogenic temperature. Temperature decrease…
