Semiconductor nanofilms as thermal phonon polarizers: competing effects of scattering selection rules and boundary mode conversion
Vasumathy Ravishankar, Navaneetha K. Ravichandran
Phonon scattering selection rules are known to control heat flow through bulk solids. Here we show that these selection rules also modulate heat flow through nanoscale semiconducto…
Bridging the continuum and the kinetic-Boltzmann theories of heat flow through generalized Knudsen numbers
Nikhil Malviya, Navaneetha K. Ravichandran
Heat conduction in semiconductor crystals is fundamentally governed by the linearized Peierls-Boltzmann equation (LPBE) for phonon transport, that arises out of a kinetic theory fo…
Examining the microscopic origin of a computationally inexpensive thermal-conductivity-based indicator for phonon hydrodynamics
Nikhil Malviya, Navaneetha K. Ravichandran
Hydrodynamic heat flow, where out-of-equilibrium phonons collectively drift in response to a temperature gradient, has attracted renewed interest following its experimental observa…
Elasticity reshapes heat flow in graphene
Navaneetha K. Ravichandran
Classical thermal transport theories that preserve rotational symmetry, predict strong anharmonic scattering of out-of-plane lattice vibrational modes called flexural phonons in fl…
Low bending rigidity and large Young's modulus drive strong flexural phonon renormalization in two-dimensional monolayers
Navaneetha K Ravichandran
Many intriguing phenomena such as the wave-like hydrodynamic heat flow, the logarithmic divergence of electrical resistivity at low temperatures and microscale kirigami are driven…
