Description: 
ZnO is one of the most important semiconducting materials in developing high-quality optical microcavities and high-efficiency ultraviolet (UV) optoelectronic devices owing to its direct wide band gap (3.37 eV) and large exciton binding energy (60 meV)[1]. Beside this, it is well known as chemical sensor since its surface interact with gases and a modification of electrical or optical properties is recorded [2]. ZnO crystallize in wurtzite structure and can be easily obtained as nanowire (NW) by different techniques (chemical or physical deposition), ensuring high surface to volume ratio available for interaction with gases. ZnO nanorods obtained by RF sputtering were investigated as conductometric gas sensors as a whole demonstrating excellent properties for H2S and H2 detection.To better understand the properties of the ZnO NWs we investigated a single NW, instead of mesh of NWs with a wide diameters distribution …
