Magnetic Properties of Mn and Fe-Implanted p-GaN
Nikoleta Theodoropoulou,M. E. Overberg,S. N. G. Chu,Arthur F. Hebard,C. R. Abernathy,Robert G. Wilson,J. M. Zavada,K. P. Lee,Stephen J. Pearton +8 more
TL;DR: The structural and magnetic properties of p-GaN implanted with high doses of Mn + or Fe + (0.1-5 at%) and subsequently annealed at 700-1000 °C were examined by transmission electron microscopy, selected-area diffraction patterns, X-ray diffraction and SQUID magnetometry as mentioned in this paper.
Journal ArticleDOI
High-speed modulation of 850-nm intracavity contacted shallow implant-apertured vertical-cavity surface-emitting lasers
G. T. Dang,William Scott Hobson,L.M.F. Chirovsky,John Lopata,M. Tayahi,S. N. G. Chu,Fan Ren,Stephen J. Pearton +7 more
TL;DR: In this article, a GaAs-AlGaAs quantum-well (850 nn) vertical-cavity surface-emitting laser with shallow implanted apertures was presented.
Journal ArticleDOI
Cathodoluminescence studies of carrier concentration dependence for the electron-irradiation effects in p-GaN
O. Lopatiuk-Tirpak,Leonid Chernyak,Yu-Lin Wang,Fan Ren,Stephen J. Pearton,Konstantin Gartsman,Yishay Feldman +6 more
TL;DR: In this paper, the authors studied the effect of hole concentration on nonequilibrium carrier lifetime in Mg-doped GaN and found that the decay of activation energy with hole concentration was consistent with Mg acceptors, indicating the involvement of the latter levels in irradiationinduced lifetime changes.
Journal ArticleDOI
Dominant factors limiting efficiency of optical spin detection in ZnO-based materials
Weimin Chen,Irina Buyanova,Akihiro Murayama,T. Furuta,Yasuo Oka,David P. Norton,Stephen J. Pearton,Andrei Osinsky,J. W. Dong +8 more
TL;DR: In this article, two dominant factors limiting the efficiency of optical spin detection in ZnO-based materials system are identified from time-resolved optical orientation and magneto-optical studies.
Journal ArticleDOI
Gallium nitride-based gas, chemical and biomedical sensors
Stephen J. Pearton,Fan Ren +1 more
TL;DR: Semiconductor-based sensors are widely used for applications in detection of particular gases and liquids, fire detection, liquid quality monitoring, biosensing and medical sensing and this group has installed hydrogen sensors at a car dealership in Orlando, FL, USA that houses a fleet of hydrogen-fuelled buses.
