$SnO_2$, a n-type metal oxide semiconductor with a wide band gap of 3.6 eV has emerged as a potent gas sensing material. The gas sensing properties of $SnO_2$ can be further enhanced by doping it with foreign metals, noble elements and metal oxides in addition to reducing it to nanometer size. In this work we have studied the gas sensing performance of tin oxide by reducing it to nanometer...

Quantum dots are nanostructured semiconductor materials whose dimension is comparable to the de Broglie wavelength of free electrons. Due to the quantum confinement effect, the motion of the electrons present in the quantum dots is restricted in all three dimensions and the electronic energy states become quantized as compared to their bulk counterparts. This quantization of energy states...
