Autor: M. M. Ramli, W. Zhang, S. R. P. Silva, S. J. Henley

Publikováno v: AIP Advances, Vol 2, Iss 3, Pp 032165-032165-8 (2012)

Direct golden orange dye molecules were used as a dispersing agent to produce suspensions of single-walled carbon nanotubes (SWCNTs) in water. Uniform, thin film networks were fabricated by vacuum filtration using different concentrations of SWCNT an

Emission rate and internal quantum efficiency enhancement in different geometrical shapes of GaN LED

Autor: N. S. A. Abdul Halim, Mukhzeer Mohamad Shahimin, Shanise Rashid, N. A. M. Ahmad Hambali, M. H. A. Wahid, M. M. Ramli

Publikováno v: AIP Conference Proceedings.

This work is based on the development of light emitting diode (LED) using different geometry of top surface on GaN p-n junction structure. Three types of LED chips are designed with different top surface to differ whether p-type layer or p contact pl

P-type surface effects for thickness variation of 2um and 4um of n-type layer in GaN LED

Autor: N. S. A. Abdul Halim, M. M. Ramli, N. A. M. Ahmad Hambali, M. H. A. Wahid, Shanise Rashid, Mukhzeer Mohamad Shahimin

Publikováno v: AIP Conference Proceedings.

The internal quantum efficiency of III-Nitrides group, GaN light-emitting diode (LED) has been considerably limited due to the insufficient hole injection and this is caused by the lack of performance p-type doping and low hole mobility. The low hole

Design and Analysis of XOR Logic Gate Based on Two-Photon Absorption

Autor: Mukhzeer Mohamad Shahimin, M. M. Ramli, N.S. Nazir, M. H. A. Wahid, N.Z. Khairuddin, Nor Azura Malini Ahmad Hambali, N.H. Hasanuddin

Publikováno v: MATEC Web of Conferences, Vol 78, p 01108 (2016)

Two-photon absorption with high intensity pump beam occurs in a SOA depends on fast phase change of a weak probe signal. This work analysed optical XOR logic function using two-photon absorption induced fast phase change. A rate equation for SOA and
