Emergent Rashba spin-orbit coupling in bulk gold with buried network of nanoscale interfaces
Shreya Kumbhakar, Banashree Debnath, Tuhin Kumar Maji +8
The Rashba effect, which plays a crucial role in fundamental materials physics and potential spintronics applications, has been engineered in diverse systems, including semiconduct…
Enhanced Phonon-Assisted Tunneling in Metal -- Twisted Bilayer Graphene Junctions
Radhika Soni, Suvronil Datta, Robin Bajaj +7
We report planar tunneling spectroscopy measurements on metal-WSe-twisted bilayer graphene heterostructures across a broad range of gate and bias voltages. The observed experim…
Probing Phonon Modes in Reconstructed twisted Homo and Hetero Bilayer System
Sushil Kumar Sahu, Robin Bajaj, Syed Ummair Ali +7
Twist angle engineering in van der Waals homo and hetero-bilayers introduces profound modifications in their electronic, optical and mechanical properties due to lattice reconstruc…
PARPHOM: PARallel PHOnon calculator for Moiré systems
Shinjan Mandal, Indrajit Maity, H R Krishnamurthy +1
The introduction of a twist between two layers of two-dimensional materials has opened up a new and exciting field of research known as twistronics. In these systems, the phonon di…
Electric field tunable superconductivity with competing orders in twisted bilayer graphene near magic-angle
Ranit Dutta, Ayan Ghosh, Shinjan Mandal +6
Superconductivity (SC) in twisted bilayer graphene (tBLG) has been explored by varying carrier concentrations, twist angles, and screening strength, with the aim of uncovering its…
Possibilities for enhanced electron-phonon interactions and high- superconductivity in engineered bimetallic nano-structured superlattices
Shinjan Mandal, Shrihari Soundararajan, Manish Jain +1
We explore theoretically the properties of engineered bimetallic nano-structured superlattices where an array of nano-clusters of a simple (single band) metal are embedded periodic…
