Abstract:
|
Ultraviolet (UV) photodetectors based on ternary Zn2GeO4 nanowire (NW) networks are
demonstrated. The devices show fast response and recovery time, which is attributed to the unique
NW-NW junction barrier dominated conductance for network devices. The UV-light induced barrier
height modulation is much faster than the oxygen adsorption/desorption processes. The wide-band
gap Zn2GeO4 NWs also exhibit high wavelength selectivity for deep UV detection. We demonstrate
that ternary oxide NW-networks are ideal building blocks for nanoscale photodetectors with
superior performance and facile fabrication processes. |
