Solar-blind ultraviolet photodetector based on graphene/vertical Ga2O3 nanowire array heterojunction
In this paper, a solar-blind ultraviolet photodetector (PD) based on the graphene/vertical Ga2O3 nanowire array heterojunction was proposed and demonstrated. To the best of our knowledge, it is the first time that vertical Ga2O3 nanowire arrays have been …
Direct laser writing of vertical junctions in graphene oxide films for broad spectral position-sensitive detectors
Heterostructures with built-in electric fields are crucial for charge separation and lateral photovoltaic effect in current position-sensitive detectors (PSDs), which have to be produced by combining semiconductors with metal or other semiconductors to form …
De-multiplexing free on-chip low-loss multimode switch enabling reconfigurable inter-mode and inter-path routing
Switching and routing are critical functionalities for a reconfigurable bandwidth-dense optical network, and great efforts had been made to accommodate mode-division multiplexing technology. Although the reconfigurable routing for spatial-mode groups between …
Dynamic near-field heat transfer between macroscopic bodies for nanometric gaps
The dynamic heat transfer between two half-spaces separated by a vacuum gap due to the coupling of their surface modes is modeled using the theory that describes the dynamic energy transfer between two coupled harmonic oscillators, each separately connected …
