SnO2 functionalized AlGaN/GaN high electron mobility transistor for hydrogen sensing applications

Wide Bandgap Semiconductor One-Dimensional Nanostructures for Applications in Nanoelectronics and Nanosensors

“…Once again, the high surface area of nanowires provides an ideal approach for enzymatic detection of biochemically important substances [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

“…Specific semiconductor materials including III-nitrides such as GaN [12][13] and InN [14][15][16], metal oxides including ZnO and SnO2 [17][18], and high-temperature materials such as SiC [19] have seen the greatest interest for chemical gas sensing applications, chiefly for the detection of H2, O2, NH3 and ethanol. There is also interest in applying these to biomarker detection [21][22][23][24][25][26][27][28][29][30].…”

Ni-doped ZnS decorated graphene composites with enhanced photocatalytic hydrogen-production performance

“…In the hydrogen production procedure, energy gap of photocatalyst has to cross H 2 O reduction potential to decompose water and generate the oxygen. Semiconductor materials have been used for H 2 production [1,2], photocatalytic degradation [3,4], and gas sensor [5,6] applications. Materials with a more negative conduction band than the reduction potential of protons, such as TiO 2 , SrTiO 3 , ZnS, CdS, are promising photocatalysts for H 2 production [7e10].…”

Pt-decorated GaN nanowires with significant improvement in H 2 gas-sensing performance at room temperature

“…The existence of H 2 gas is particularly destructive in aircraft and gas pipeline applications [1,32,33].…”

“…Another important application of H 2 sensor is in fuel cells [2]. This presents an attractive alternative to fossil fuel combustion engine, where H 2 is consumed in vehicles for their efficiency, versatility and environmental friendliness [23,32]. Besides, H 2 is used in rechargeable nickel metal-hydrides (NiMH) batteries for personal electronics and as portable or stationary emergency power [25].…”
