We have synthesized two new Eu-based compounds, EuSr2Bi2S4F4 and Eu2SrBi2S4F4 which are derivatives of Eu3Bi2S4F4, an intrinsic superconductor with Tc = 1.5 K. They belong to a tet…
Ultrasensitive Self-powered large area planar GaN UV-photodetector using reduced graphene oxide electrodes
Nisha Prakash, Manjri Singh, Gaurav Kumar +5
A simplistic design of a self-powered UV-photodetector device based on hybrid r-GO/GaN is demonstrated. Under zero bias, the fabricated hybrid photodetector shows a photosensivity…
Room temperature multiferroism in polycrystalline thin films of gallium ferrite
Monali Mishra, Amritendu Roy, Ashish Garg +2
Sol-gel deposited (010) textured polycrystalline thin films of gallium ferrite (GaFeO3 or GFO) on n-Si(100) and Pt/Si(111) substrates are characterized for room temperature multife…
FIB synthesis of Bi2Se3 1D nanowires demonstrating the co-existence of Shubnikov-de Haas oscillations and linear magnetoresistance
Biplab Bhattacharyya, Alka Sharma, V P S Awana +2
Since the discovery of topological insulators (TI), there are considerable interests in demonstrating metallic surface states, their shielded robust nature to the backscattering an…
High yield synthesis and liquid exfoliation of two-dimensional belt like hafnium disulphide
Harneet Kaur, Sandeep Yadav, Avanish K. Srivastava +5
Producing monolayers and few-layers in high yield with environment-stability is still a challenge in hafnium disulphide (HfS2), which is a layered two-dimensional material of group…
Effect of disorder on superconductivity and Rashba spin-orbit coupling in LaAlO3/SrTiO3 interfaces
G. Singh, A. Jouan, S. Hurand +6
A rather unique feature of the two-dimensional electron gas (2-DEG) formed at the interface between the two insulators LaAlO3 and SrTiO3 is to host both gate-tunable superconductiv…
Flux free growth of superconducting FeSe single crystals
P. K. Maheshwari, L. M. Joshi, Bhasker Gahtori +4
We report flux free growth of superconducting FeSe single crystals by an easy and versatile high temperature melt and slow cooling method for first time. The room temperature XRD o…
Effect of impurity substitution on band structure and mass renormalization of the correlated FeTeSe superconductor
