บทคัดย่อ/คำอธิบาย :

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.
