  • Congratulations to Mr. Bikash Das for his recent work with Dr. Arnab Biswas and Prof. Nitin Chattopadhyay (Department of Chemistry, Jadavpur University)  concerning a memcapacitive gel which has been published in "Advanced Functional Materials". Please feel free to use any facilities in the lab. Do not hesitate to contact PhD students/Post docs. [
  • Congratulations to Mr. Rahul Pramanik for his recent work with Prof. Asim Guchhait's group at P K College, Contai which has been published in "Energy Fuels" . We welcome any expression of interest for collaboration with our group member/s using in-house facilities. [
  • April 19, 2023 - Ms. Anudeepa Ghosh has successfully defended her thesis on "Phonon and Dielectric Properties of Layered Antiferromagnets". Her thesis mainly focusses on the spin-phonon coupling and magnetodielectric effect in two-dimensional vdW antiferromagnets. She has utilized low-temperature Raman scattering and dielectric measurement set-up to record the data. Congratulations Anudeepa!
  • Our first experience with beamline science and technique (spectromicroscopy) - @Elettra - We would like to thank DST for the travel funds, Elettra for the DA. For technical help - Dr Alexey BARINOV (coordinator), Marek KOPCIUSZYNSKI and most importantly, our collaborator - Dr. Sanjoy Kr Mahatha (IUC Indore)
  • Our proposal on "Soil Health Monitoring Device and Remote Data Logger" has been selected for Technology Incubation under MeitY TIDE 2.0 EiR @ IIM Calcutta.  Congratulations to Mainak. We are also thankful to past students (mainly, Avishek and Saikat) who have contributed to the construction of the circuit and modification. We are looking for enthusiastic project students who may work with us for the final prototype. [Link:]
  • Mainak and Sujan have "finally" finalized a recipe for the fabrication of circuits (400 - 500 nm) with nanostructure in EBL. Thanks to Dr. KDM Rao and his group for the continuous support. We also thank the operator (Mr. Manish) of the EBL. 
  • CVT set up for the crystal growth working regularly. We are looking for collaboration for the growth of novel vdW materials. [responsible students: Bikash Das, Sujan Maity]
  • Optical upright microscope (under CSS facility) has been installed recently.
