    • Wake potential and induced forces for protons in solids 

      Al-Ani, Riayhd K. A. (Universiti Malaysia Perlis, 2011)
      The wake potential associated with the passage of swift protons through a solid material using cylindrical coordinates is studied. Full results of the wake potential as a function of space when a proton moves parallel with ...
    • Wake potential of swift ions in copper target 

      Nabil Janan, Al-Bahnam; Khalid A., Ahmad; Abdulla, Ahmad Rasheed (Universiti Malaysia Perlis, 2016)
      We investigate the interaction of proton with a solid target, describing the wake effects by taking fitted parameters with experimental values of energy loss function ELF for copper using the dielectric function of random ...
    • Wet transfer process for MEMS freestanding PMMA/Graphene membrane development 

      Norliana, Yusof; Badariah, Bais; Norhayati, Soin; Burhanuddin, Yeop Majlis (Universiti Malaysia Perlis (UniMAP), 2020-12)
      Process of transferring poly (methyl methacrylate) (PMMA)/Graphene layer to form a freestanding membrane requires a proper method to ensure that the membrane is well suspended with high graphene coverage. This paper ...
    • X-ray and dielectric studies of ferroelectric phase in the Ba1-x(Yb0.5 Na0.5)x TiO3 system for low doping level 

      Khemakhem, L.; Kriaa, I.; Derbel, M.; Abdelmoula, N. (Universiti Malaysia Perlis, 2009)
      Ceramics of solid solution Ba1-x(Yb0.5Na0.5)xTiO3 were sintered in the temperature range 1220-1400°C. Dielectric properties of ceramics belonging to the whole composition domain were investigated in a broad range of ...
    • X-ray diffraction and mossbauer spectrometry investigations of invar nanoparticles produced by mechanical alloying 

      Boudinar, N.; Djekoun, A.; Chebli, A.; Otmani, A.; Bouzabata, B.; Greneche, J. M. (Universiti Malaysia Perlis, 2010)
      Fe-Ni ultra-fine particles were prepared by mechanical alloying and phase transformation during mecahnical alloying was studied. Results show that phase transformation tendency is different during mechanical alloying of ...
    • Xenon flash lamp annealing of large area silicon photodetector 

      Raid, A. Ismail; Omar, A. Sultan; Razak, A. Al-Salam (Universiti Malaysia Perlis, 2012)
      Xenon flash lamp with 100 μm pulse duration was used to enhance the performance of large area (1cm2) diffused silicon photodiodes. Leakage current, rectification, and photoresponse of silicon photodiodes after lamp annealing ...
    • Z-Scan measurement of optical nonlinearities for (3GO) dye 

      Ali H., Al-Hamdani (Universiti Malaysia Perlis, 2013)
      In this paper a sensitive single-beam technique for measuring both the nonlinear refractive index and nonlinear absorption coefficient for 3GO dye were reported. Descriptions for the experimental details and theoretical ...
