Md. Mamun-Or-Rashid, MPhil

Assistant Professor, Department of Physics, DUET, Gazipur

Mr. Md. Mamun-Or-Rashid is currently working as an Assistant Professor in the Department of Physics at Dhaka University of Engineering & Technology (DUET), Gazipur, and is also a PhD scholar at the Graduate School of Science & Engineering, Saitama University, Japan. He was born in Banaripara, Barishal, in 1992. He completed his SSC (Secondary School Certificate) in 2006 from Uttarkul Secondary School, Banaripara, and his HSC (Higher Secondary Certificate) in 2008 from Amrita Lal Dey College, Barishal. In 2012, he earned his B.Sc. (Bachelor of Science) in Physics, followed by an M.Sc. (Master of Science) in 2013 from Jahangirnagar University, and an M.Phil. (Master of Philosophy) in Physics from DUET, Gazipur, in 2022. He has experience in growing thin films using spray pyrolysis, spin coating, hydrothermal routes, chemical bath deposition, and electrodeposition techniques, as well as fabricating ferrite materials through solid-state reaction methods. He is also proficient in UV-Vis spectroscopy for optical characterization (absorbance, transmittance, and reflectance) of various solutions, thin films, and layers. Additionally, he has expertise in 4-point probe measurements for thin film/layer resistivity, impedance analysis for magnetic and electrical measurements, data analysis and fitting using Origin, and working with Microsoft Office, Excel, and PowerPoint. He is also skilled in fabricating solar cells using the thermal evaporation technique and characterizing intermediate band solar cells (IBSC) through photoluminescence (PL), external quantum efficiency (EQE), and two-wavelength excited photocurrent (TWEPC) measurements.
