Material and Device Architecture Engineering Toward High Performance Two-Dimensional (2D) Photodetectors
Photodetectors based on two-dimensional (2D) nanostructures have led to a high optical response, and a long photocarrier lifetime because of spatial confinement effects. Since the discovery of graphene, many different 2D semiconductors have been developed and utilized in the ultrafast and ultrasensitive detection of light in the ultraviolet, visible, infrared and terahertz frequency ranges. Thi...
متن کاملHigh-Performance and Self-Powered Deep UV Photodetectors Based on High Quality 2D Boron Nitride Nanosheets
High-quality two-dimensional (2D) crystalline boron nitride nanosheets (BNNSs) were grown on silicon wafers by using pulsed plasma beam deposition techniques. Self-powered deep ultraviolet (DUV) photodetectors (PDs) based on BNNSs with Schottky contact structures are designed and fabricated. By connecting the fabricated DUV photodetector to an ammeter, the response strength, response time and r...

15 صفحه اولTwo-Dimensional Material Nanophotonics
The emerging two-dimensional (2D) materials exhibit a wide range of electronic properties, ranging from insulating hexagonal boron nitride (hBN), semiconducting transition metal dichalcogenides (TMDCs) such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), to semi-metallic graphene. The plethora of 2D materials together with their heterostructures, which are free of the traditional...
متن کاملHigh-performance nanotube-enhanced perovskite photodetectors
Organic-inorganic perovskites have already shown a tremendous potential for low-cost light-harvesting devices. Yet, the relatively low carrier mobilities in bulk perovskites still prevent large-area devices with performances competing with state-of-the-art technologies. Here, we tackle this fundamental challenge by incorporating single-wall carbon nanotubes within a perovskite matrix by means o...
