Signatures of moiré intralayer biexcitons and exciton-phason coupling in WSe2/WS2 heterostructures
Ranju Dalal, Harsimran Singh, Rwik Dutta +6
Interactions among electronic and lattice degrees-of-freedom are foundational to various phases in condensed-matter physics, yet the dynamic interplay between excitonic and phononi…
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…
Controlling particle-hole symmetry of fractional quantum hall states in trilayer graphene
Simrandeep Kaur, Harsimran Singh, Kenji Watanabe +5
We present a detailed experimental study of the particle-hole symmetry (PHS) of the fractional quantum Hall (FQH) states about half filling in a multiband system. Specifically, we…
