Several methods have been used to prepare titania films, and these include chemical vapour deposition (CVD), pulsed laser deposition, reactive sputtering and sol-gel deposition. The sol-gel technique ...

Two types of thin films illustrated in Figure 1 were d eposited by Ti-Zn alternative sputtering using a tripole magnetron sputtering apparatus. Figure 2 shows XRD patterns of single and triple layer ...

Measuring the band gap of materials is vital in the nanomaterial, semiconductor, and solar industries. This article illustrates how the band gap of a material can be established from its UV absorption ...
