Electrochemically Programmed, Spatially Selective Functionalization of Silicon Nanowires

In2O3 nanowires as chemical sensors

We present an approach to use individual In2O3 nanowire transistors as chemical sensors working at room temperature. Upon exposure to a small amount of NO2 or NH3 , the nanowire transistors showed a decrease in conductance up to six or five orders of magnitude and also substantial shifts in the threshold gate voltage. These devices exhibited significantly improved chemical sensing performance c...

An investigation into the conversion of In2O3 into InN nanowires

Straight In2O3 nanowires (NWs) with diameters of 50 nm and lengths ≥2 μm have been grown on Si(001) via the wet oxidation of In at 850°C using Au as a catalyst. These exhibited clear peaks in the X-ray diffraction corresponding to the body centred cubic crystal structure of In2O3 while the photoluminescence (PL) spectrum at 300 K consisted of two broad peaks, centred around 400 and 550 nm. The ...

Selective functionalization of In2O3 nanowire mat devices for biosensing applications.

A strategy to covalently attach biological molecules to the electrochemically active surface of indium oxide nanowire (In2O3 NW) mat devices is presented. A self-assembled monolayer (SAM) of 4-(1,4-dihydroxybenzene)butyl phosphonic acid (HQ-PA) was generated on an indium tin oxide (ITO)-coated glass and In2O3 NWs surface. The chemical steps required for surface derivatization were optimized on ...

Sn-doped In2O3 nanowires: enhancement of electrical field emission by a selective area growth

Selective area growth of single crystalline Sn-doped In2O3 (ITO) nanowires synthesized via vapor-liquid-solid (VLS) method at 600°C was applied to improve the field emission behavior owing to the reduction of screen effect. The enhanced field emission performance reveals the reduction of turn-on fields from 9.3 to 6.6 V μm-1 with increase of field enhancement factors (β) from 1,621 to 1,857 aft...
