Evidence of Rotational Fröhlich Coupling in Polaronic Trions
Maxim Trushin, Soumya Sarkar, Sinu Mathew +9
Electrons commonly couple through Fröhlich interactions with longitudinal optical phonons to form polarons. However, trions possess a finite angular momentum and should therefore c…
Enhanced hydrodynamic transport in near magic angle twisted bilayer graphene
Mohammad Zarenia, Indra Yudishtira, Shaffique Adam +1
Using the semiclassical quantum Boltzmann theory and employing the Dirac model with twist angle-dependent Fermi velocity we obtain results for the electrical resistivity, the elect…
Phase coherent transport in bilayer and trilayer MoS2
Leiqiang Chu, Indra Yudhistira, Hennrik Schmidt +3
Bilayer MoS2 is a centrosymmetric semiconductor with degenerate spin states in the six valleys at the corners of the Brillouin zone. It has been proposed that breaking of this inve…
Electronic Ground State in Bilayer Graphene with Realistic Coulomb Interactions
Jia Ning Leaw, Ho-Kin Tang, Pinaki Sengupta +3
Both insulating and conducting electronic behaviors have been experimentally seen in clean bilayer graphene samples at low temperature, and there is still no consensus on the natur…
Gauge phonon dominated resistivity in twisted bilayer graphene near magic angle
I. Yudhistira, N. Chakraborty, G. Sharma +5
Recent experiments on twisted bilayer graphene (tBG) close to magic angle show that a small relative rotation in a van der Waals heterostructure greatly alters its electronic prope…
First-principles quantum corrections for carrier correlations in double-layer two-dimensional heterostructures
Martin-Isbjörn Trappe, Derek Y. H. Ho, Shaffique Adam
We present systematic ab initio calculations of the charge carrier correlations between adjacent layers of two-dimensional materials in the presence of both charged impurity and st…
