III-V Nanowire and Quantum Dot Devices for Optoelectronics and Biosensing
This community develops semiconductor nanostructures—primarily gallium arsenide (GaAs) and indium arsenide (InAs) nanowires and quantum dots—to build high-performance photodetectors, solar cells, and field-effect transistor biosensors.
The research focuses on the growth and engineering of III-V compound semiconductors, with a heavy emphasis on GaAs and InAs materials. Key structures include core-shell nanowires, quantum wells, and quantum dots, often fabricated using molecular beam epitaxy or chemical etching. These structures are integrated into specific device architectures, notably tunnel field-effect transistors (TFETs) and double-gate transistors, to enhance electrical performance. A significant portion of the work addresses optical applications, including infrared photodetection, solar cell efficiency, and nonlinear optical responses. Additionally, a substantial strand of research applies silicon nanowires and GaAs-based FETs for label-free biosensing, targeting the detection of cancer cells, DNA, and pathogens.
The community is most heavily concentrated in research tracked for Gallium, representing 6.6% of all Gallium research, and Arsenic, representing 7.0% of all Arsenic research. Indium research also forms a major component, accounting for 5.1% of that element’s tracked output.
The community comprises 31,216 papers, with the highest publication volume in Applied Physics Letters, Journal of Applied Physics, and Journal of Crystal Growth.
Recent work continues to refine III-V nanowire solar cells and long-wavelength infrared photodetectors, while also exploring machine learning approaches for predicting nonlinear optical properties in GaAs/AlGaAs structures and developing CRISPR-functionalized silicon nanowire sensors for pathogen detection.
