Magneto-Seebeck coefficient of Fermi-liquid in three-dimensional Dirac/Weyl semimetal
F. R. Pratama, Riichiro Saito, Nguyen T. Hung
We investigate dissipationless magneto-Seebeck effect in three-dimensional Dirac/Weyl semimetal. The Hall resistivity and thermoelectric Hall coefficient exhibit…
Enhanced thermoelectric performance by van Hove singularities in the density of states of type-II nodal-line semimetals
Nguyen T. Hung, Jyesta M. Adhidewata, Ahmad R. T. Nugraha +1
The effects of the unique density of states (DOS) of a topological type-II nodal-line semimetal (NLS) on its thermoelectric (TE) transport properties are investigated through a com…
Anomalous Phonon-mode Dependence in Polarized Raman Spectroscopy of Topological Weyl Semimetal TaP
Kunyan Zhang, Xiaoqi Pang, Tong Wang +8
Topological Weyl semimetals (WSMs) have attracted widespread interests due to the chiral Weyl fermions and surface Fermi arcs that enable unique optical and transport phenomena. In…
Tunable Circular Dichroism and Valley Polarization in the Modified Haldane Model
Marc Vila, Nguyen Tuan Hung, Stephan Roche +1
We study the polarization dependence of optical absorption for the modified Haldane model, which exhibits antichiral edge modes in presence of sample boundaries and has been argued…
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…
