Percolating SnO2 nanowire network as a stable gas sensor: Direct comparison of long-term performance versus SnO2 nanoparticle films

Preparation of WO3 network squares for ultrasensitive photodetectors

“…Among these architectures, network structures can function as both devices and interconnections, and thus are expected to play a key role in the production of next generation of nanoscale electronic and optoelectronic devices [4][5][6]. Moreover, the networks usually show some novel and interesting properties superior to those of simple nanostructures.…”

Highly sensitive CO sensors based on cross-linked TiO2 hollow hemispheres

“…5(b)). The thermal stability of the NTHH sensor is excellent, which is superior to that of gas sensors based on 3-dimensional mesoporous nanoparticle film and comparable to that of gas sensors based on 2-dimensional nanowire network [26]. The dispersion is lower than 10% which is quite acceptable taking into account the signal ripple of our system (∼10%) as seen in Fig.…”

Surface-dominated negative photoresponse of phosphorus-doped ZnSe nanowires and their detecting performance

“…In addition, 1-D semiconductor nanostructures like NWs with their typical high aspect ratio, that is, a length-to-diameter ratio of 20 or larger, have been seen as favorable candidates for future sensors [18]. Their extremely high surface-to-volume ratios and single-crystalline characteristics make them have great potential for use as highly sensitive gas sensors [19][20][21][22][23]. Sensors based on semiconductor nanowires have particularly attracted much attention due to their great miniaturization potential and quick diffusion of gas molecules, consequently leading to faster response and recovery times [24].…”
