Optical properties of pseudomorphic Ge1−xSnx (x = 0 to 0.11) alloys on Ge(001)
Medikonda, Manasa; Muthinti, Gangadhara R.; Vasić, Relja; Adam, Thomas N.; Reznicek, Alexander; Wormington, Matthew; Malladi, Girish; Kim, Yihwan; Huang, Yi-Chiau; Diebold, Alain C. (Journal of Vacuum Science & Technology B, Nanotechnology and Microelectronics: Materials, Processing, Measurement, and Phenomena, 2014)The characterization of the optical properties of pseudomorphic Ge1-xSnx/Ge/Si (x=0 to 0.11) alloys from the IR to UV is presented. The Ge1-xSnx alloys were epitaxially grown on relaxed Ge grown on Si. Rutherford backscattering ... -
Scalable fabrication of coupled NV center - photonic crystal cavity systems by self-aligned N ion implantation
Schröder, Tim; Walsh, Michael; Zheng, Jiabao; Mouradian, Sara L.; Li, Luozhou; Malladi, Girish; Bakhru, Hassaram; Lu, Ming; Stein, Aaron; Heuck, Mikkel; Englund, Dirk (2017, 2017)Towards building large-scale integrated photonic systems for quantum information processing, spatial and spectral alignment of single quantum systems to photonic nanocavities is required. Here, we demonstrate spatially ... -
Synthesis and properties of ferromagnetic nanostructures embedded within a high-quality crystalline silicon matrix via ion implantation and nanocavity assisted gettering processes
Malladi, Girish; Huang, Mengbing; Murray, Thomas; Novak, Steven; Matsubayashi, Akitomo; LaBella, Vincent; Bakhru, Hassaram (Journal of Applied Physics, 2014)Integrating magnetic functionalities with silicon holds the promise of developing, in the most dominant semiconductor, a paradigm-shift information technology based on the manipulation and control of electron spin and ...
