Dr. Sabah M. Mohammad currently serving as a Senior Lecturer at Institute of Nano Optoelectronics Research and Technology (INOR), Universiti Sains Malaysia (USM). During 2018, he was working as Teaching fellow at INOR-Universiti Sains Malaysia (USM). He has published a patent on the fabrication of nano-size junction LED device. He also has authored over 22 academic papers related to his research area. his researches interests are growth and fabrication of the ZnO, GaN, Graphyne, Graphyne oxide, Porous Si, and Porous GaN, as well as the design and fabrication of optoelectronic devices and gas sensors such as LED, Photodetectors. He started his research career (from 1993-1999) as department head of research group for the electro-glass department at Atomic Energy Commission, Iraq. Latter from 2001-2010. With his Ph.D. Degree study, he worked as a Graduate Research Assistant (GRA), attached with the school of physics, USM, Malaysia. His role was to teach the undergraduate and master students in their project dissertation and research works. In 1991. he received his bachelor’s degree in Science (BSc), Physics, at the school of physics, Salahaddin University, Iraq (SUI). In 2013, he received his master (MSc) degree in the solid state, at the school of physics, USM, by mode program of coursework, with the title of project “Metal-Semiconductor-Metal photodetector”. He completed his Ph.D. Degree in 2017, at the school of physics, USM. His doctorate was in the solid state with the research area of “Applied and engineering physics”, [Semiconductor of fabrication (thin Film, Epitaxy and Nano Structured)]. The title of his thesis was “Growth of ZnO Nanorods Using Hydrothermal and Modified Chemical Deposition for Devices Applications”.
