About
Dr. Partha Sarathi Padhi is currently a Postdoctoral Researcher in the Department of Solid State Sciences at Ghent University, Belgium. His research focuses on the atomic layer deposition (ALD)-based synthesis of functional materials for catalytic CO₂ hydrogenation, with an emphasis on environmental and energy applications.
Prior to his current role, Dr. Padhi completed a postdoctoral tenure in the MEMS Department at the Indian Institute of Technology (IIT) Bombay, where he developed expertise in plasma-enhanced chemical vapor deposition (PECVD) techniques for carbide-based materials and their integration into 3D thermal neutron detectors.
He earned his Ph.D. in Materials Science from the Oxide Nanoelectronics Laboratory at Raja Ramanna Centre for Advanced Technology (RRCAT), India. His doctoral research focused on the fabrication and comprehensive characterization of high-k metal oxide nanolaminates for high-density energy storage applications. Utilizing techniques such as ALD, pulsed laser deposition (PLD), and RF sputtering, he synthesized a range of binary metal oxides (TiO₂, Al₂O₃, ZnO, MgO, ZrO₂, HfO₂) and engineered nanolaminate (NL) structures with tailored sublayer thicknesses. These systems were extensively characterized using XRR, XRD, RBS, spectroscopic ellipsometry, AFM, SEM, TEM, SIMS, and XPS.
His work revealed exceptional dielectric properties (e.g., high-k values ~670, low dielectric loss ~0.17) attributed to Maxwell–Wagner interfacial polarization and quantum confinement effects. These phenomena were systematically tuned through control of layer thicknesses and growth conditions, providing valuable insights into the electronic, dielectric, and optical behavior of nanoscale multilayers.
Research Expertise:
- Thin film synthesis via ALD, PLD, PECVD, RF sputtering, and thermal evaporation
- Growth and engineering of metal oxide nanolaminates (e.g., Al₂O₃/TiO₂, Al₂O₃/ZnO, MgO/ZnO)
- Advanced structural and morphological characterization using GIXRD, XRR, RBS, SIMS, AFM, SEM, TEM, and spectroscopic ellipsometry
- Photoemission and spectroscopic techniques including UPS, XPS, PL, and Resonant PES
- Electrical and dielectric measurements: impedance spectroscopy (IS), I-V, C-V, C-f, and pulsed IV techniques
- Band alignment studies and valence band offset determination in oxide heterostructures
- Lithographic processing and device fabrication for MIM and MOS capacitor structures
- Evaluation of dielectric performance, polarization, relaxation, and conduction mechanisms in ultrathin dielectric stacks
- Proficient in FIB-based cross-sectional TEM sample preparation
- Synchrotron-based spectroscopy (Indus-1 and Indus-2 beamlines, RRCAT)
Research Interests:
- Catalysis and H2 Generation
- Physics of dielectrics and semiconductors
- Interface and surface phenomena in heterostructures
- Design and integration of quantum and neuromorphic electronic devices
- Charge transport and defect engineering in functional materials
- Synthesis and application of emerging 2D materials (e.g., MoS₂, graphene, MXenes)
- Development of oxide-based devices for memristors, resistive switching, and biocompatible applications
Dr. Padhi is enthusiastic about exploring new interdisciplinary research avenues and is keen to contribute to the development of advanced materials for scalable, real-world technologies.
