Pranab Das

Hello! This is Pranab. Welcome to my homepage. I am a researcher at Singapore Synchrotron Light Source, National University of Singapore. I am working in the field of experimental Condensed Matter Physics. I am interested in studying electronic structure of novel and functional materials by spin- and angle-resolved photoemission spectroscopy (ARPES). We are working on various novel materials including topological insulators, Weyl semimetals, superconductors, transition metal dichalcogenides, and transition metal oxides. Due to the extreme surface sensitivity of photoelectron spectroscopy techniques, we need in-situ sample/surface preparation under ultra-high vacuum conditions. ARPES also requires atomically flat surfaces, therefore we need high-quality single crystalline samples. We usually cleave or exfoliate ex-situ grown single crystals under ultra-high vacuum, or sputter and anneal to clean and re-crystallize the surfaces. We also specialize in material synthesis, density functional theory calculations, and collaborate with other synchrotron facilities and research groups worldwide. We have in-situ Pulsed LASER Deposition system to grow thin films, we are also able to de-cap ex-situ grown films by heating and annealing. For more details about our work, please visit the research and publications pages.

Besides, I am a computer science enthusiast. I try writing codes to make things a little better. You can find my open-source projects on GitHub. You may also check out some of my notes and tutorials, which are still work in progress. Thank you for stopping by, and wish you a great time!
