    • 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 ...

    • A Novel AC technique for high quality porous GaN 

      Ainorkhilah, Mahmood; Naser Mahmoud, Ahmed, Dr.; Yuhamdan, Yusof; Yam, Fong Kwong, Dr.; Chuah, Lee Siang, Dr.; Husnen R., Abd; Zainuriah, Hassan (Electrochemical Science Group (ESG), 2013-04)
      In this paper, we report the formation of porous GaN films under a novel alternatingcurrent (sine-wave a.c. (50 Hz)) photo-assisted electrochemical etching (ACPEC) conditions. The ac formed porous GaN with excellent ...
