Excess entropy and breakdown of semiclassical description of thermoelectricity in twisted bilayer graphene close to half filling
Bhaskar Ghawri, Phanibhusan S. Mahapatra, Shinjan Mandal +9
In moiré systems with twisted bilayer graphene (tBLG), the amplification of Coulomb correlation effects at low twist angles () is a result of nearly flat low-energy electronic b…
Evidence of Lifshitz transition in thermoelectric power of ultrahigh mobility bilayer graphene
Aditya Jayaraman, Kimberly Hsieh, Bhaskar Ghawri +2
Resolving low-energy features in the density of states (DOS) holds the key to understanding wide variety of rich novel phenomena in graphene based 2D heterostructures. Lifshitz tra…
Observation of excess resistance anomaly at resistive transitions in Ag/Au nanostructures
Phanibhusan S Mahapatra, Subham Kumar Saha, Rekha Mahadevu +8
The resistive transition in nanocomposite films of silver (Ag) nanoclusters of ~ 1 nm diameter embedded in gold (Au) matrix exhibits an anomalous resistance peak at the onset of th…
Mis-orientation controlled cross-plane thermoelectricity in twisted bilayer graphene
Phanibhusan S Mahapatra, Bhaskar Ghawri, Kenji Watanabe +3
The introduction of 'twist' or relative rotation between two atomically thin van der Waals (vdW) membranes gives rise to periodic Moire potential, leading to a substantial altercat…
Current-voltage characteristics in Ag/Au nanostructures at resistive transitions
Saurav Islam, Rekha Mahadevu, Subham Kumar Saha +7
Transitions to immeasurably small electrical resistance in thin films of Ag/Au nanostructure-based films have generated significant interest because such transitions can occur even…
Seebeck Coefficient of a Single van der Waals Junction in Twisted Bilayer Graphene
Phanibhusan S. Mahapatra, Kingshuk Sarkar, H. R. Krishnamurthy +2
When two planar atomic membranes are placed within the van der Waals distance, the charge and heat transport across the interface are coupled by the rules of momentum conservation…
