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…
Non-universal Scaling of Thermoelectric Efficiency in 3D and 2D Thermoelectric Semiconductors
Kevin Octavian, Eddwi H. Hasdeo
We performed the first-principles calculation on common thermoelectric semiconductors , , , and in bulk three-dimension (3D) and tw…
Strain Effects on Band Structure and Dirac Nodal-line Morphology of ZrSiSe
Bernardus Rendy, Eddwi H. Hasdeo
The Dirac nodal-line semimetals (DNLS) are new promising materials for technological applications due to its exotic properties, which originate from band structures dispersion and…
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…
