Multiple Softening Q-vectors Driving a Cascade of CDW Phases in
Zheng-Hong Li, Yung-Ting Lee, Yu-Chan Tai +8
Charge density wave (CDW) formation in two-dimensional materials is governed by complex competing lattice instabilities that remain incompletely understood. Here, we investigate th…
Revealing the Charge Density Wave caused by Peierls instability in two-dimensional NbSe
Yung-Ting Lee, Po-Tuan Chen, Zheng-Hong Li +10
The formation of a charge density wave (CDW) in two-dimensional (2D) materials caused by Peierls instability is a controversial topic. This study investigates the extensively debat…
Atomically-thin metallic Si and Ge allotropes with high Fermi velocities
Chin-En Hsu, Yung-Ting Lee, Chieh-Chun Wang +4
Silicon and germanium are the well-known materials used to manufacture electronic devices for the integrated circuits but they themselves are not considered as promising options fo…
Unfolding optical transition weights of impurity materials for first-principles LCAO electronic structure calculations
Yung-Ting Lee, Chi-Cheng Lee, Masahiro Fukuda +1
A method to analyze optical transitions is developed by combining the Kubo-Greenwood formula with the unfolding method to construct an unfolded electronic band structure with optic…
Structure map of AB type 2D materials by high-throughput DFT calculations
Masahiro Fukuda, Jingning Zhang, Yung-Ting Lee +1
By high-throughput calculations based on the density functional theory, we construct a structure map for AB type monolayers of 3844 compounds which are all the combinations of…
Tight-binding calculations of optical matrix elements for conductivity using non-orthogonal atomic orbitals: Anomalous Hall conductivity in bcc Fe
Chi-Cheng Lee, Yung-Ting Lee, Masahiro Fukuda +1
We present a general formula for the tight-binding representation of momentum matrix elements needed for calculating the conductivity based on the Kubo-Greenwood formula using atom…
Realization of intrinsically broken Dirac cones in graphene via the momentum-resolved electronic band structure
Chi-Cheng Lee, Masahiro Fukuda, Yung-Ting Lee +1
A way to represent the band structure that distinguishes between energy-momentum and energy-crystal momentum relationships is proposed upon the band-unfolding concept. This momentu…
