Photoconductivity calculations of bilayer graphene from first principles and deformation-potential approach
Yijun Ge, Timothy S. Fisher
We report first-principles calculations of electron-phonon coupling in bilayer graphene and the corresponding contribution to carrier scattering. At the phonon point, electrons…
Atomistic Simulation of Phonon and Magnon Thermal Transport across the Ferro-Paramagnetic Transition
Yanguang Zhou, Julien Tranchida, Yijun Ge +2
A temperature-dependent approach involving Green-Kubo equilibrium atomic and spin dynamics (GKEASD) is reported to assess phonon and magnon thermal transport processes accounting f…
Dramatic increase in the thermal boundary conductance and radiation limit from a Nonequilibrium Landauer Approach
Jingjing Shi, Xiaolong Yang, Timothy S. Fisher +1
Thermal boundary conductance (TBC) is critical in many thermal and energy applications. A decades-old puzzle has been that many of the measured TBCs, such as those well characteriz…
Phonon Eigenspectrum-Based Formulation of the Atomistic Green's Function Method
Sridhar Sadasivam, Umesh V. Waghmare, Timothy S. Fisher
While the atomistic Green's function (AGF) method has the potential to compute spectrally resolved phonon transport across interfaces, most prior formulations of the AGF method pro…
Reduced work function of graphene by metal adatoms
Merid Legesse, Fedwa El Mellouhi, El Tayeb Bentria +4
In this paper, the work function of graphene doped by different metal adatoms and at different concentrations is investigated. Density functional theory is used to maximize the red…
Thermal Transport Across Metal Silicide-Silicon Interfaces: First-Principles Calculations and Green's Function Transport Simulations
Sridhar Sadasivam, Ning Ye, James Charles +4
In this work, we use a combination of first-principles calculations under the density functional theory framework and heat transport simulations using the atomistic Green's functio…
