General Conditions for Axis Dependent Conduction Polarity
Poulomi Chakraborty, Brian Skinner, Penghao Zhu
Axis-Dependent Conduction Polarity (ADCP) refers to the phenomenon in which electrical transport within a single material is p-type along one crystallographic direction and n-type…
Interband State Transfer in Double-Gated Bilayer Graphene at High Electric Field
Margherita Melegari, Brian Skinner, Ignacio Gutierrez-Lezama +1
The band structure of Bernal-stacked bilayer graphene can be tuned using double-gated transistors to apply a perpendicular electric field that generates an interlayer potential ene…
Design Principles for Topological Thermoelectrics
Brian Skinner, Poulomi Chakraborty, Joshua Scales +1
Conventional metals, insulators, and semimetals are constrained by fundamental limitations in terms of their thermoelectric performance. Topological materials offer certain feature…
Nonlinear thermoelectric effects as a means to probe quantum geometry
Xu Yang, Brian Skinner
The quantum geometric tensor, which has the quantum metric and Berry curvature as its real and imaginary parts, plays a key role in the transport properties of condensed matter sys…
Refining the Two-Band Model for Highly Compensated Semimetals Using Thermoelectric Coefficients
Ian Leahy, Andrew Treglia, Gang Cao +2
In studying compensated semimetals, the two-band model has proven extremely useful in capturing electrical conductivity under magnetic field, as a function of density and mobility…
