Topological transitions to Weyl states in bulk BiSe: Effect of hydrostatic pressure and doping
Sudip Kumar Saha, Hrishit Banerjee, Manoranjan Kumar
BiSe, a layered three dimensional (3D) material, exhibits topological insulating properties due to presence of surface states and a band gap of 0.3 eV in the bulk. We study…
Effective separation of photogenerated electron-hole pairs by radial field facilitates ultrahigh photoresponse in single semiconductor nanowire photodetectors
Shaili Sett, Arup Kumar Raychaudhuri
We report an investigation on the observation of ultrahigh photoresponse (photogain, G_Pc>106) in single nanowire photodetectors of diameter < 100 nm. The investigation which is a…
Structural Phase Dependent Giant Interfacial Spin Transparency in W/CoFeB Thin Film Heterostructure
Surya Narayan Panda, Sudip Majumder, Arpan Bhattacharyya +3
Pure spin current has transfigured the energy-efficient spintronic devices and it has the salient characteristic of transport of the spin angular momentum. Spin pumping is a potent…
Signatures of a spin-1/2 cooperative paramagnet in the diluted triangular lattice of YCuTiO
S. Kundu, Akmal Hossain, Pranava Keerthi S +11
We present a combination of thermodynamic and dynamic experimental signatures of a disorder driven dynamic cooperative paramagnet in a 50% site diluted triangular lattice spin-1/2…
Experimental Evidence of Stable 2 Phase on the Surface of Layered 1-TaTe
Indrani Kar, Kapildeb Dolui, Luminita Harnagea +6
We report on the low-energy electronic structure of Tantalum ditelluride (1-TaTe), one of the charge density wave (CDW) materials from the group V transition metal dichalco…
Prediction on Properties of Rare-earth 2-17-X Magnets Ce2Fe17-xCoxCN : A Combined Machine-learning and Ab-initio Study
Anita Halder, Samir Rom, Aishwaryo Ghosh +1
We employ a combination of machine learning and first-principles calculations to predict magnetic properties of rare-earth lean magnets. For this purpose, based on training set con…
