A theory of electroded thin thermopiezoelectric plates subject to large driving voltages
(American Institute of Physics, 19941101)We first reduce existing equations for nonlinear thermoelectroelasticity to the case of large electric fields, small strains, and infinitesimal temperature variations. These equations are then specialized to the case of ... 
Unsteady nanoscale thermal transport across a solidfluid interface
(American Institute of Physics, 20080915)We simulate unsteady nanoscale thermal transport at a solidfluid interface by placing cooler liquidvapor Ar mixtures adjacent to warmer Fe walls. The equilibration of the system towards a uniform overall temperature is ... 
Lattice thermal conductivity of a silicon nanowire under surface stress
