Dr. Kiran Shankar Hazra

Associate Professor (Scientist-E)

The Low Dimension Materials and Devices (LDMD) Group at INST Mohali drives innovation in nanostructured 2D semiconductors with artificial edges, nanoscopic sensors and devices on 2D platforms, and nanoscale optics/electronics via contact engineering, charge trapping, quasiparticle manipulation, and LSPR. We pioneer advanced SERS platforms for disease diagnostics and material quality monitoring, AI tools for Raman-based analyte fingerprinting, and fundamental light-matter interactions at the nanoscale—bridging nanoscopic electronics and spectroscopy, aiming practical applications. Our group encourages Wild and Original ideas !

  • Anirban et al. have developed  a novel metal free SERS substarte on Nano-structured layered Black Phosphorus by fabricating hotspot array, where a controlled nano-patterning process has been demonstrated using low power focused Laser irradiation.

    Nanoscale, 2019, 11, 16245

  • Renu et. al. have demonstrated an experimental and computational investigation on the effect of the external direction-dependent electric field on the phonon characteristics and electronic band structure of MoS2. They have presented a systematic correlation in the lattice perturbation brought about by the external electric field with the phonon characteristics and electronic band structure of MoS2.

    Journal of Applied Physics, 2020, 127, 14510

  • Anirban et al. have demonstrated the existence of pressure-induced partial phase transition in few-layer Black Phosphorus (BP), probed by high-pressure Raman spectroscopy. The study reveals the existence of a metastable state, where both Black Phosphorus (orthorhombic) and Blue Phosphorus (rhombohedral) phases can coexist.
