GaN terahertz photodetectors for the reststrahlen Gap of intersubband optoelectronics
Durmaz Sağır, Habibe; Nothern, Denis; Brummer, Gordie; Moustakas, Theodore D.; Paiella, Roberto (Ieee, 2017)Terahertz intersubband photodetectors are developed based on GaN/AlGaN quantum wells grown on a semi-polar GaN substrate, covering the frequency range that is fundamentally inaccessible to existing III-V semiconductor ... -
Graphene terahertz plasmons: A combined transmission spectroscopy and raman microscopy study
Tantiwanichapan, Khwanchai; Wang, Xuanye; Durmaz, Habibe; Li, Yuyu; Swan, Anna K.; Paiella, Roberto (Amer Chemical Soc, 2017)Graphene provides a promising materials platform for fundamental studies and device applications in plasmonics. Here we investigate the excitation of THz plasmon polaritons in large-area graphene samples on standard oxidized ... -
III-nitride terahertz photodetectors for the reststrahlen gap of intersubband optoelectronics
Paiella, Roberto; Durmaz, Habibe; Sudradjat, Faisal F.; Nothern, Denis; Brummer, Grace C.; Zhang, Wan; Woodward, Jeff; Moustakas, Theodore D. (Spie-Int Soc Optical Engineering, 2017)We report the development of terahertz intersubband photodetectors based on GaN/AlGaN quantum wells, covering the frequency range that is fundamentally inaccessible to existing III-V semiconductor devices due to Reststrahlen ... -
Strain-engineered SiGe nanomembrane quantum-well infrared photodetectors
Durmaz, Habibe; Sookchoo, Pornsatit; Cui, X.; Jacobson, Ronald B.; Savage, Donald E.; Lagally, M. G.; Paiella, Roberto (Ieee, 2017)SiGe quantum-well nanomembranes, where stress from lattice mismatch is relaxed via elastic strain sharing rather than defect formation, are used to develop intersubband photodetectors showing improved performance compared ...
