Non-Hermiticity induced Exceptional Points and Skin Effect in the Dice-Haldane Model
Ronika Sarkar, Arka Bandyopadhyay, Awadhesh Narayan
The interplay of topology and non-Hermiticity has led to diverse, exciting manifestations in a plethora of systems. In this work, we systematically investigate the role of non-Herm…
Electrically switchable giant Berry curvature dipole in silicene, germanene and stanene
Arka Bandyopadhyay, Nesta Benno Joseph, Awadhesh Narayan
The anomalous Hall effect in time-reversal symmetry broken systems is underpinned by the concept of Berry curvature in band theory. However, recent experiments reveal that the nonl…
Direct Opto-Electronic Imaging of 2D Semiconductor - 3D Metal Buried Interfaces
Kiyoung Jo, Pawan Kumar, Joseph Orr +10
The semiconductor-metal junction is one of the most critical factors for high performance electronic devices. In two-dimensional (2D) semiconductor devices, minimizing the voltage…
Nitrogen Doped Graphene Quantum Dots as Possible Substrates to Stabilize Planar Conformer of Au 20 Over its Tetrahedral Conformer: A Systematic DFT Study
Sharma SRKC Yamijala, Arkamita Bandyopadhyay, Swapan K Pati
Utilizing the strengths of nitrogen doped graphene quantum dot (N-GQD) as a substrate, here in, we have shown that one can stabilize the catalytically more active planar Au 20 (P-A…
Electronic properties of zigzag, armchair and their hybrid quantum dots of graphene and boron-nitride with and without substitution: A DFT study
Sharma SRKC Yamijala, Arkamita Bandhyopadyay, Swapan K Pati
Spin-polarized density functional theory calculations have been performed on armchair graphene quantum dots and boron-nitride quantum dots (A-G/BN-QDs) and the effect of carbon/bor…
