Does Topology Enhance Thermoelectric Efficiency? A Case Study in Bismuthene
Muhammad Gaffar, Sasfan Arman Wella, Eddwi Hesky Hasdeo
Two-dimensional (2D) bismuth (Bi) layer, known as bismuthene, exhibits topological bulk states due to large spin-orbit coupling that inverts the bands. Using the tight-binding…
Kerr effect in tilted nodal loop semimetals
Johan Ekström, Eddwi H. Hasdeo, M. Belén Farias +1
We investigate the optical activity of tilted nodal loop semimetals. We calculate the full conductivity matrix for a band structure containing a nodal loop with possible tilt in th…
Electron hydrodynamics of anomalous Hall materials
Eddwi H. Hasdeo, Johan Ekström, Edvin G. Idrisov +1
We study two-dimensional electron systems in the hydrodynamic regime. We show that a geometrical Berry curvature modifies the effective Navier-Stokes equation for viscous electron…
Origin of the flat band in heavily Cs doped graphene
N. Ehlen, M. Hell, G. Marini +6
A flat energy dispersion of electrons at the Fermi level of a material leads to instabilities in the electronic system and can drive phase transitions. Here we introduce a method t…
Optimal band gap for improved thermoelectric performance of two-dimensional Dirac materials
Eddwi H. Hasdeo, Lukas P. A. Krisna, Muhammad Y. Hanna +3
Thermoelectric properties of two-dimensional (2D) Dirac materials are calculated within linearized Boltzmann transport theory and relaxation time approximation. We find that the ga…
Thermoelectric properties of two-dimensional Dirac materials
Eddwi H. Hasdeo, Lukas P. A. Krisna, Ahmad R. T. Nugraha
We performed Boltzmann transport calculation to obtain the Seebeck coefficient, electrical conductivity, electronic thermal conductivity, and thermoelectric figure of merit (ZT) fo…
