Thin Films and Photovoltaics
Faculty Members: Dr. Dhriti Sundar Ghosh
Research Overview: The division focuses on the basic understanding of the growth of thin films (metals, oxides, nitrides, organics) and their deposition techniques (physical vapor, chemical vapor, solution processed) so that their morphological and electro-optical properties can be tailored according to the target application. The acquired know-how is then applied in energy-efficient thin film devices such as organic light emitting diodes (OLEDs), transistors and photovoltaic (solar) cells to make them inexpensive, more stable and efficient. The division also has core competence in photovoltaic cells (organic and perovskite cells), their optical modelling, fabrication and characterization.
High Energy Physics
Research Overview: The mission of the High Energy Physics Division is to understand the origin of matter through high energetic probe, where the journey is starting from the nucleus to nucleons and the zoo of short-lived hadrons and then to their fundamental building blocks. In this journey of research, there are many unsolved and unsettled problems, where our group is involved with the topics of low scale neutrino mass generation, dark matter, baryon asymmetry of the Universe, quark-hadron phase transition, signals of quark gluon plasma and origin of its nearly perfect fluid nature.
High Energy Physics
Research Overview: The division of Nonlinear Optics and Photonics primarily focuses on the design and development of coherent sources based on optical parametric oscillators (OPOs), as well as second/third-harmonic generation (SHG/THG) and sum/difference-frequency generation (SFG/DFG) techniques, enabling access to unprecedented wavelength regions from the ultraviolet to the deep mid-infrared in all time-scale from continuous-wave to ultrafast. Various novel architectures/approaches and nonlinear materials are investigated. Further, fundamental studies in OPOs and optical nonlinear phenomena for the generation of optical frequency combs are carried on, with the aim of reducing the cost and complexity of existing sources, and finding many applications.
