Biography

Dr. Ekta Yadav is an Assistant Professor (Grade-I) in the Department of Physics and Materials Science and Engineering (PMSE) at Jaypee Institute of Information Technology (JIIT), Noida. She specializes in pulsed laser deposition (PLD) of perovskites, complex oxide thin films, and two-dimensional materials for spintronic applications. Before joining JIIT, she served as an Assistant Professor in the Department of Physics at Starex University, Gurugram.

Dr. Yadav earned her PhD from the Indian Institute of Technology (IIT) Indore in Jan 2024, where she investigated the correlated structural, electronic, and magnetic properties of PLD-grown thin films of functional perovskite materials. She subsequently pursued postdoctoral research at the Indian Institute of Science (IISc), Bangalore, focusing on the superconducting diode effect in layered materials such as graphene, hBN, NbSe2, and other emerging quantum materials. Her research integrates advanced thin-film fabrication, 2D materials device synthesis using a microscope equipped micromanipulator, and low-temperature transport measurements, contributing to the advancement of next-generation spintronic and quantum devices.

Dr. Yadav has published twelve peer-reviewed publications in international journals. She has presented research papers in more than 5 national and international conferences. Till now, she has reviewed manuscripts from international journals such as Journal of Physics Condensed Matter (JPCM), Journal of Physics D: Applied Physics, Physica Scripta, etc. With over eight years of teaching and research experience, Dr. Yadav is currently interested in exploring spin-based devices for new-age technology.

Research Highlights
  • Synthesis of high-quality epitaxial PrNiO3 thin films using pulsed laser deposition technique and study the influence of deposition parameters, such as epitaxial strain, elemental doping, pressure, and oxygen stoichiometry to tune the metal–insulator transition, offering insights into correlated electron systems.
  • Fabrication of highly-ordered magneto-resistive Sr2FeMoO6 double perovskite thin films with controlled cation arrangement, establishing a direct link between structural ordering, electronic transport, and magneto-resistive properties.
  • Exploring various methods, such as different background gases, substrate orientation, and thickness variation, to enhance cation ordering in Sr2FeMoO6 double perovskite thin films.
  • Carefully optimizing the pulsed laser deposition protocols for complex oxides, perovskites, and double perovskite thin films. This also facilitates achieving crystallinity, stoichiometry, and phase purity of thin films, which are key steps for functional device integration.
  • Investigated van der Waals heterostructures based on 2D superconducting materials such as graphene, NbSe2, and 2D magnet such as MnBi2Te4. This research enabled the study of magnetism, superconductivity, and topological phenomena in low-dimensional systems.
