Pressure induced emergence of visible luminescence in : Effect of structural distortion in optical behaviour
Debabrata Samanta, Pinku Saha, Bishnupada Ghosh +4
We report emergence of photoluminescence at room temperature in trigonal at high pressures. Enhancement in intensity with pressure is found to be driven by increase…
Pressure induced lattice expansion and phonon softening in layered
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +2
We report high pressure X-ray diffraction and a detailed systematic Raman measurements on sample, which is mechanically exfoliated from a single crystal. A few new Bragg pe…
High Pressure Structural Investigation on Lead-Free Piezoelectric -
Anshuman Mondal, Pinku Saha, Bishnupada Ghosh +4
The solid solution - (BCZT) has become a promising member of the lead-free piezoelectric materials because of its exceptiona…
Anomalous compressibility in 1T MoTe single crystal:High pressure Raman and structural studies
Bishnupada Ghosh, Pinku Saha, Goutam Dev Mukherjee
A detailed high pressure study is carried out on 1T MoTe using X-ray diffraction(XRD) and Raman spectroscopy measurements upto about 30.5 GPa. High pressure XRD meas…
Pulsed laser deposition of highly c-axis oriented thin films of BSTS topological insulator
Atul Pandey, Sourabh Singh, Bishnupada Ghosh +3
We report the growth of highly c-axis oriented topological insulator (TI) BiSbTe1.5Se1.5 (BSTS) thin films by pulsed laser deposition (PLD) technique. The various growth parameters…
High pressure anomalies in exfoliated : Resonance Raman and X-ray diffraction studies
Pinku Saha, Bishnupada Ghosh, Aritra Mazumder +1
Detailed high pressure Resonance Raman () Spectroscopy and X-ray diffraction () studies are carried out on 3-4 layered obtained by liquid exfoliation. Analysis of…
