Muhammad Kashif, Muhammad Faroow; Uda, Hashim, Prof. Dr.; Syed Muhammad Usman, Ali Shah, Dr.; Zafar Hussain, Ibupoto; Willander, Magnus, Prof. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)Impedance spectroscopy is used to study the frequency dependent electrical parameters such as impedance, dielectric constant and conductivity of ZnO nanorods MSM structure in the range of 1 Hz to 10MHz under atmospheric ... -
Study of ZnO films on SiO2/Si substrate by sol–gel spin coating method
Foo, Kai Loong; Uda, Hashim, Prof. Dr.; M., Kashif (Universiti Malaysia Perlis (UniMAP), 2012-06-18)ZnO films, type of the metal-oxide semiconductor promised a wide range of application, especially in optical and medical field. ZnO prepared from zinc acetate dehydrate as a precursor as a solvent exhibit high crytallinity ... -
Subnanometer poly-silicon gap structure formation: Comparison study between size expansion and size reduction
Uda, Hashim, Prof. Dr.; Nazwa, Taib; Thikra, S. Dhahi (American Institute of Physics., 2012)This study describes the comparison among the three fabrication methods of an array of poly-silicon nanogap structures. The three different methods are size expansion technique (SET), size reduction technique (SRT) and ... -
The usage of max 262 as a programmable low pass filter for nanogap automated permittivity measurement system
Azizullah, Saifullah; Uda, Hashim, Prof. Dr. (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)The Nanogap Automated Permittivity Measurement System (APMS) are fabricated for low cost, portable and label free DNA hybridization detection kit. The nanogap capacitor can react as a DNA sensor. The difference ... -
UV-vis studies on interaction of silver nanoparticles(SNPs) with protein from chicken meat
M.K., Nahar; Zarina, Zakaria, Dr.; Uda, Hashim, Prof. Dr. (Universiti Malaysia Perlis (UniMAP), 2012-06-18)We examine the direct interaction between chicken protein and the surface of silver nanoparticles (SNPs) by using UV-vis spectrophotometer. The spectral changes observed in SNPs after mixing with chicken protein are ...
