      One the major requirements for sensing devices is its sensitivity. This paper presents the design, analysis and simulation of various types of MEMS based microcantilevers shapes and their influence on sensing sensitivity. ...

    • A simple oxidation technique for quantum dot dimension shrinkage and tunnel barriers generation 

      Madnarski Sutikno; Uda, Hashim, Prof. Dr.; Zul Azhar, Zahid Jamal, Prof. Dr. (Elsevier B.V., 2007-05)
      The tunnel barriers generation and the quantum dot size shrinkage play a significant role in single-electron transistor (SET) fabrication. Because the numerically etch indicators were not found, the technical indicators, ...

    • Simulation of 1GHz center frequency SAW using CST software for biosensor application 

      Mohd Rosydi, Zakaria; Uda, Hashim, Prof. Dr.; M. H. I., Mohd Amin; Tijjani Adam, Shuwa; M. Wesam, Al-Mufti (IDOSI Publications, 2013)
      Surface Acoustic Wave (SAW) is a one of the essential components that used for sensor application to detect in various fields. The high center frequencywill improve the sensitivity of SAW biosensor. Therefore, it's very ...
