Minimum and maximum conductance of a thin film layer bridged interface: the role of anharmonicity and layer thickness
Jingjie Zhang, Rouzbeh Rastgarkafshgarkolaei, Carlos A. Polanco +4
We study the role of anharmonicity at interfaces with an added intermediate layer designed to facilitate interfacial phonon transport. Our results demonstrate that while in the har…
Thermal management and non-reciprocal control of phonon flow via optomechanics
Alireza Seif, Wade DeGottardi, Keivan Esfarjani +1
Engineering phonon transport in physical systems is a subject of interest in the study of materials and plays a crucial role in controlling energy and heat transfer. Of particular…
Unexpectedly High Cross-plane Thermoelectric Performance in Layered Carbon Nitrides
Zhidong Ding, Meng An, Shenqiu Mo +7
Organic thermoelectric (TE) materials create a brand new perspective to search for high-efficiency TE materials, due to their small thermal conductivity. The overlap of pz orbitals…
Negative differential resistance in molecular junctions: application to graphene ribbon junctions
Hosein Cheraghchi, Keivan Esfarjani
Using self-consistent calculations based on Non-Equilibrium Green's Function (NEGF) formalism, the origin of negative differential resistance (NDR) in molecular junctions and quant…
Divergence of effective mass in 'Uncorrelated State Percolation' Model
Seyyed Mahdi Fazeli, Keivan Esfarjani
We want to answer the question of whether the divergence in the effective mass in metal-insulator transition (MIT) in 2DEG is in the same universality class as percolation. We use…
Some analytic results in coherent quantum transport
Mohammad Mardaani, Keivan Esfarjani
A quantum wire of uniform cross section (but with eventual disorder) with three regions: dot, left lead, and right lead, is considered. Assuming that the same unitary transformatio…
