Temperature induced band convergence, intervalley scattering and thermoelectric transport in p-type PbTe
Ransell D'Souza, José D. Querales-Flores, Jiang Cao +2
Achieving high valley degeneracy (i.e. "band convergence") in a material usually results in considerably enhanced thermoelectric properties. However, it is still unclear why this s…
Electron-phonon scattering and thermoelectric transport in -type PbTe from first principles
Ransell D'Souza, Jiang Cao, José D. Querales-Flores +2
We present a first principles based model of electron-phonon scattering mechanisms and thermoelectric transport at the L and valleys in <200b>-type PbTe, accounting for thei…
Strain induced large enhancement of thermoelectric figure-of-merit () in transition metal dichalcogenide monolayers ZrX (X= S, Se, Te)
Ransell D'Souza, Sugata Mukherjee, Sohail Ahmad
Two-dimensional group IV transition-metal dichalcogenides have encouraging thermoelectric applications since their electronic and lattice properties can be manipulated with strain.…
Enhancement of thermoelectric figure-of-merit of Graphene upon BN-doping and sample length reduction
Ransell D'Souza, Sugata Mukherjee
Using first-principles density functional perturbation theory based calculations of length-dependent lattice thermal conductivity (\k{appa} L ) and using our previously calculated…
Length dependent lattice thermal conductivity of single \& multi layered hexagonal boron nitride: A first-principles study using the Callaway-Klemens \& real space super cell methods
Ransell D'Souza, Sugata Mukherjee
The phonon dispersion, density of states, Grüneisen parameters, and the lattice thermal conductivity of single- and multi-layered boron nitride were calculated using first-principl…
Influence of Interface Geometry on Phase Stability and Bandgap Engineering in Boron Nitride substituted Graphene: A Combined First-principles and Monte Carlo Study
Ransell D'Souza, Sugata Mukherjee, Tanusri Saha-Dasgupta
Using combination of Density Functional Theory and Monte Carlo simulation, we study the phase stability and electronic properties of two dimensional hexagonal composites of boron n…
