个人简介
My name is Ananya Chattaraj, recently joined as a post doc fellow at Indian beam line in Photon Factory, KEK, Japan under the affiliation of Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) Jakkur, Bangalore. The areas in which I am interested are; Transition metals, Phase transition, A15 compounds, Nanomaterials, X-ray Crystallography, Electronic Structure, Topological Phases, Magnetism, and Spintronics.
I have completed my Ph.D. under the guidance of Prof. Aloke Kanjilal (Advisor) and Prof. Vijay Kumar (Co-Advisor) at Shiv Nadar University, India. The title of my thesis is “Study of growth, structure, and electronic properties of β tungsten for spintronic applications”. I have 5 years of research experience in Material Physics. At the starting, of the first year, I was assigned as a Junior Research Fellow (JRF) under a project of the Department of Science and Technology (DST), India under project #DST/EMR/2014/000971. The topic of the project was “The impact of oxygen-induced defects in TiO₂-based resistive switching devices”. The objectives I have full filled in this tenure are the following; developmentof an RF/DC sputtering system for thin-film growth, deposition of materials like W, TiO₂, determination of the crystal structures, characterization of W/TiO₂/W heterostructures, and fabricating the resistive switching devices. Next, I joined as a Ph.D. Scholar in the Department of Physics. The main focus of my thesis problem is to search and or study/new materials for future spintronic applications. My area of expertise is the growth of thin films by sputter deposition, and electron beam deposition techniques and study their detailed atomic structure, phase formation through grazing incidence X-ray diffraction system, and determine the electronic structure from X-ray Absorption Spectroscopy for spintronic applications. I have mostly worked on the β phase of Tungsten (W), and W-based A15 compounds, which will be the potential candidates for future spin-based devices, especially in spin logic devices or magnetic random access memory devices. In this aspect, the phase formation is very crucial, and for that, the structural study is mostly has been done with the help of Synchrotron facilities. I am familiar to work in Synchrotron-based X-ray diffraction and also gained knowledge of data analysis in X-ray crystallography. In addition, I have experienced working with UV-Visible Spectroscopy and Scanning Electron Microscopy. I have acquired a detailed knowledge of fitting X-ray Photoelectron Spectroscopy (XPS) data, and X-ray Absorption Spectroscopy (XAS) data through Casa and Athena software, respectively. Moreover, I am also expertise in ab initio calculations (density functional theory, ab initio molecular dynamics simulations). This tool is very useful to study the materials from a different perspective and is mostly used in my thesis work to support the experimental findings. In this regards the electronic structures of transition metal and metal oxides are very important, especially the energy bands, from which one can proposed the materials applicable for either spin-based devices or energy storage devices. Currently, I am working on the halide based perovskite materials for optoelectronic applications with one of the Ph.D. students in my research group.
I have worked at Synchrotron facilities, BL-1, and BL-12, Raja Ramanna Centre for Advanced Technology (RRCAT), Indore, India, and received a grant from DST to do the measurement in Indian beam-line (BL18B) of the Synchrotron radiation facility at the Photon Factory (PF), KEK, Tsukuba, Japan. 2020. Over time, I have developed an aptitude for research project management, problem-solving and analytical skills. I have presented my research work in some national and international seminars and conferences and attended many webinars and workshops during my Ph.D. I used assigned for giving training on sputtering to undergraduate (B.Sc. Research) and Ph.D. students. I was the mentor of two Opportunities for Undergraduate Research (OUR) Programs; (i)“Resistive Switching Behaviour of Graphene-Based Memory Devices” May 2019 and (ii) “Exploration of Optical Properties Of Tungsten Oxide For Photochromic Application” May 2020.
