Anisotropic structural dynamics of monolayer crystals revealed by femtosecond surface x-ray scattering
I-Cheng Tung, Aravind Krishnamoorthy, Sridhar Sadasivam +22
X-ray scattering is one of the primary tools to determine crystallographic configuration with atomic accuracy. However, the measurement of ultrafast structural dynamics in monolaye…
Theory of Thermal Relaxation of Electrons in Semiconductors
Sridhar Sadasivam, Maria K. Y. Chan, Pierre Darancet
We compute the transient dynamics of phonons in contact with high energy "hot" charge carriers in 12 polar and non-polar semiconductors, using a first-principles Boltzmann transpor…
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…
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…
Thermal Transport Across Metal Silicide-Silicon Interfaces: An Experimental Comparison between Epitaxial and Non-epitaxial Interfaces
Ning Ye, Joseph P Feser, Sridhar Sadasivam +4
Silicides are used extensively in nano- and microdevices due to their low electrical resistivity, low contact resistance to silicon, and their process compatibility. In this work,…
Büttiker probes for dissipative phonon quantum transport in semiconductor nanostructures
K. Miao, S. Sadasivam, J. Charles +3
Theoretical prediction of phonon transport in modern semiconductor nanodevices requires atomic resolution of device features and quantum transport models covering coherent and inco…
Electron-Phonon Coupling and Thermal Conductance at a Metal-Semiconductor Interface: First-principles Analysis
Sridhar Sadasivam, Umesh V. Waghmare, Timothy S. Fisher
The mechanism of heat transfer and the contribution of electron-phonon coupling to thermal conductance of a metal-semiconductor interface remains unclear in the present literature.…
