Comparative Assessment of Thermal Transport Theories: Dual-Channel Mechanism Dictates Heat Transport in Ultralow- Materials
Soham Mandal, Ashutosh Srivastava, Tanmoy Das +3
Anomalous heat transport in strongly anharmonic crystalline solids poses both a fundamental challenge to the theoretical understanding and an opportunity for thermoelectric and the…
Freezing of the tetrahedral amorphous network in supercooled water triggers crystallization towards LDA ice
Ashutosh Srivastava, Pankaj A. Apte
In this work, we provide mechanistic insight into the initial stages of formation of ice across the limit of stability of supercooled water. Such an analysis is particularly import…
Phonon Band Center: A Robust Descriptor to Capture Anharmonicity
Madhubanti Mukherjee, Ashutosh Srivastava, Abhishek Kumar Singh
Understanding anharmonicity is crucial for designing materials with desired lattice thermal conductivity. Designing a material descriptor that effectively captures anharmonicity wh…
Anisotropic in-plane lattice thermal conductivity in bilayer ReS2
Ashutosh Srivastava, Nikhilesh Maiity, Abhishek Kumar Singh
The significantly weak interlayer coupling strength and puckered structure provide the novel layer-tolerant and anisotropic features in two-dimensional (2D) ReS2. These unique feat…
Enhanced heat dissipation and lowered power consumption in electronics using two-dimensional hexagonal boron nitride coatings
Karthik R, Ashutosh Srivastava, Soumen Midya +9
Miniaturization of electronic components has led to overheating, increasing power consumption and causing early circuit failures. Conventional heat dissipation methods are becoming…
