Pressure-Driven Phase Evolution and Optoelectronic Properties of Lead-free Halide Perovskite RbTeBr
Suvashree Mukherjee, Asish Kumar Mishra, K. A. Irshad +2
The structural, vibrational, and optical properties of RbTeBr have been investigated under high pressure using synchrotron X-ray diffraction, Raman spectroscopy, photolumin…
Soft mode induced structural phase transition in BaZnTeO at high pressure
Bidisha Mukherjee, Surajit Adhikari, Mrinmay Sahu +5
In this paper, we present a thorough investigation of vibrational, structural, and electronic properties of perovskite-type rhombohedral BaZnTeO (BZTO) under systematic app…
Emission enhancement and bandgap narrowing in under pressure
Debabrata Samanta, Suvashree Mukherjee, Asish Kumar Mishra +5
Pressure-induced emission enhancement and bandgap narrowing in vacancy-ordered halide double perovskite are extensively investigated through photoluminescence and abso…
High pressure ferroelectric-like semi-metallic state in doped
Mrinmay Sahu, Bishnupada Ghosh, Bobby Joseph +1
We have conducted a detailed high-pressure (HP) investigation on doped using angle-resolved x-ray diffraction, Raman spectroscopy, dielectric permittivity and dc res…
