Wide-bandgap Zn2GeO4 nanowire networks as efficient ultraviolet photodetectors with fast response and recovery time
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 ...
Crystallographic alignment of ZnO nanorod arrays on Zn2GeO4 nanocrystals : promising lattice-matched substrates
We demonstrated that ternary Zn2GeO4 crystals could be used as potential lattice-matched substrates for ZnO nanorod array growth. Single-crystalline Zn2GeO4 nanowires were used as substrates for crystallographic alignment ...
Kinking-induced structural evolution of metal oxide nanowires into single-crystalline nanorings
We report an innovative method to fabricate single-crystalline nanorings based on the conventional vapor−liquid−solid (VLS) mechanism. The controllable formation of kinks in functional oxide nanowires (NWs) can be employed ...
Network-enhanced photoresponse time of Ge nanowire photodetectors
We demonstrated that the photoresponse time of Ge nanowire (NW) photodetectors could be greatly improved by using percolated NW networks (instead of single NW) as the active detection channels. Although the reset time for ...
Ultrahigh-performance solar-blind photodetectors based on individual single-crystalline In2Ge2O7 nanobelts
Solar-blind photodetectors are designed from individual In2Ge2O7 nanobelts using a standard photolithography technique. The detectors demonstrated high sensitivity and selectivity towards the solar-blind spectrum, fast ...
Room temperature CO gas sensing using Zn-doped In2O3 single nanowire field effect transistors
We demonstrate a room temperature sensing of CO gas (1–5 ppm) using high performance single Zn-doped In2O3 nanowire field effect transistors (Zn–In2O3 NW-FETs). Zn–In2O3 nanowires were grown in a horizontal CVD furnace; ...
