X-ray diffraction analysis indicates that samples of pure and Ti-doped were polycrystalline with a crystal orientation along (113) plane. The average grain size increases with the increasing titanium content. Surface morphology was studied through a Scanning Electron Microscope (SEM) and Atomic Force Microscopy (AFM), which reveal that grains are columnar in shape. UV-visible transmission spectroscopy reveals that the deposited films are transparent within a visible range. The value of the optical bandgap exhibits a decrease from 1.93 eV to 1.48 eV as titanium concentration increases. Gas sensitivity measurements at 30°C. showed a decrease in sensitivity with the increase of doping and gas concentration. 2020-06-24T04:11:04Z 2020-06-24T04:11:04Z 2020-04 Article International Journal of Nanoelectronics and Materials, vol.13(2), 2020, pages 221-232 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/65224 http://ijneam.unimap.edu.my en Universiti Malaysia Perlis (UniMAP) |
