Electrical conductivity, mobility and carrier concentration in Nb2O5 films: effect of NH4OH molarity
Marwa, K. Abood; Evan, T. Salim; Jehan, A. Saimon; Aseel Abdulkreem Hadi (Universiti Malaysia Perlis (UniMAP), 2021-07)This work presents the effect of NH4OH molarities on the electrical characteristics of Nb2O5 films prepared using the precipitation method. Hall Effect measurements proved the formation of n-type Nb2O5 films. The carrier ... -
Meso-porous-like tungsten oxide structure: a study on some physical properties at different deposited temperatures
Farhan, A. Mohamed; Azhar, I. Hassan; Evan T., Salim (Universiti Malaysia Perlis (UniMAP), 2022-10)Polycrystalline tungsten oxide (WO3) thin films were prepared using the spray pyrolysis method at various substrate temperatures (200, 250, 300, 350, and 400 °C) on the quartz substrate. The X-ray diffraction pattern showed ... -
Niobium Pentoxide Thin Film Prepared using Simple Colloidal Suspension for Optoelectronic Application
Abood, M. K.; Salim, E. T.; Saimon, J. A. (Universiti Malaysia Perlis (UniMAP), 2018-04)In this study, thin‐film microstructures of polymorphous niobium pentoxide were successfully prepared at a low temperature. Spin coating was employed to deposit the colloidal suspension before and after ultrasonic ...
