Topological insulators and Weyl semimetals have demonstrated a helicity-dependent
photocurrent (HDPC). In contrast, Dirac semimetals (DSMs) possess chirality-degenerate …

AEIn2As2 (AE= Ca, Sr, Ba), as a new crucial nonmagnetic thermoelectric candidate, needs
to be understood in terms of its potential electronic structure properties and topological …

We have assessed mechanical bending as a powerful controlling tool for the electronic
structure and optical properties of phosphorene nanoribbons. We use state-of-the-art density …

We investigate disorder-driven transitions between trivial and topological insulator (TI)
phases in two-dimensional (2D) systems. Our study primarily focuses on the Bernevig …

Experimental results that BaIn 2 As 2 and Ca (Sr) In 2 As 2, which are the same class of
alkali metal compounds, belong to different structural phases have puzzled the current …

The collapse of Landau levels under an electric field perpendicular to the magnetic field is
one of the distinctive features of Dirac materials. So is the coupling of lattice deformations to …

In topological semimetals, nodes appear at symmetry points in the Brillouin zone as a result
of band inversion, and yield quasirelativistic massless fermions at low energies. Cd 3 As 2 is …

Topological insulators and semimetals have exotic surface and bulk states with massless
Dirac or Weyl fermions, demonstrating microscopic transport phenomenon based on …

The directionality of steering charge carriers is of great importance for the application of two-
dimensional (2D) materials. Using the generalized Bloch theorem coupled with the self …
