About

Dr. Kshetra Dehury working as an Assistant Professor in School of Physics, Gangadhar Meher University Amruta Vihar, Sambalpur, Odisha. Kshetra Mohan Dehury received his B. Sc B. Ed. (Physics) from Regional Institute of Education, Bhubaneswar, Utkal University (A constituent unit of NCERT, New Delhi, Under Ministry of Education, Govt. of India) and M. Sc (Physics) from Jiwaji University, Gwalior (NAAC Accredited A++ University Grade University). He has completed Full-time Ph.D. under the supervision of Prof. G. Vijaya Prakash, at the Department of Physics, Indian Institute of Technology Delhi, India, since July 2018. His current research work mainly focus on structural dependent exciton features Inorganic-Organic hybrid semiconductors in the form of thin films, single crystal and colloidal 2D quantum dots. He has presented his research work at several national/international workshop and conferences, including nanoGe IPEROP 23 (Kobe, Japan). Dr. Kshetra Mohan Dehury has gained expertise on Thin Film deposition (spin coating technique and Thermal evaporation deposition technique), Single Crystal growth, Colloidal 2D nanoparticle synthesis, instrumental handling such as High resolution optical microscope, UV-VIS-NIR spectrophotometer, Scanning electron microscope (SEM) and EDAX elemental mapping technique, Nonlinear spectroscopy techniques such as Two-photon absorption spectroscopy, Time resolved photoluminescence spectroscopy (TRPL), Transient absorption spectroscopy etc.

Research Area

My research area is mainly focus on synthesis of various Metal Halide perovskite semiconductors (Thin Film, Singe Crystal platelets and Colloidal 2D nanoparticle solution) and studied their structural and optical properties. Linear and nonlinear optical investigation of structurally modified room temperature Mott-type exciton of various self-assembled Inorganic-Organic (IO) hybrid semiconductors is carried out by using several techniques such as Advance Multifunctional Microscope (attached with CW diode laser (Ex:400 nm), Xenon Lamp (Ex:365 nm), Mercury Lamp and High intensity Femtosecond Ti:Sapphire laser (Ex:800 nm, 120 fs, 84 MHz), UV-VIS spectrophotometer). Structural characterization is carried out by using Glancing angle Thin Film XRD, Single Crystal XRD. Nonlinear properties of Metal Halide perovskite semiconductors is carried out by using Two-photon absorption spectroscopy, Time resolved photoluminescence spectroscopy (TRPL), Transient absorption pump-probe spectroscopy etc.
