III-V Semiconductor Nanowires and Quantum Structures for Solar Energy and Infrared Optics
This community develops advanced semiconductor materials, specifically gallium arsenide and indium-based nanowires and quantum wells, to build high-efficiency solar cells, infrared photodetectors, and nonlinear optical devices.
The work centers on the epitaxial growth and characterization of III-V compound semiconductors, with a heavy emphasis on gallium arsenide (GaAs), indium arsenide (InAs), and aluminum gallium arsenide (AlGaAs) structures. Recurring technical approaches include molecular beam epitaxy and the engineering of quantum dots, quantum wells, and core-shell nanowires. These structures are primarily applied in multijunction and tandem solar cells, including concentrator photovoltaics and laser power converters, as well as in infrared photodetectors and nonlinear optical components. The research also addresses the integration of these III-V materials with silicon substrates for hybrid device architectures.
The community is most heavily represented in research tracked for arsenic, constituting 7.1% of that element's literature, and gallium, at 6.7%. It also holds a significant share of indium research at 4.6%.
The community comprises 27,129 papers, published primarily in Applied Physics Letters, Journal of Applied Physics, and Journal of Crystal Growth.
Recent work continues to focus on the efficiency of III-V nanowire solar cells, the development of long-wavelength infrared photodetectors using type-II superlattices, and the modeling of nonlinear optical responses in GaAs/AlGaAs nanostructures.
