Dr. Lary H. Slewa, lecturer at Salahaddin University-Erbil, Kurdistan Region, received his PhD degree in 2021 in Physics (nanotechnology for biochemical applications) from Salahaddin University-Erbil through a split-site program with Universiti Sains Malaysia. I obtained my M.Sc. degree in solid state (thin film and nanotechnology) from Salahaddin University-Erbil in 2014. I have published 10 research papers in scientific journals. I’m interested in nanomaterial fabrication and characterization by using chemical and physical technology, where I have used films in many applications, such as solar cells, gas, optoelectronics, thin film EGFET for pH sensors, multilayer characteristics, etc.
