In this paper, we propose a broadband tunable metamaterial absorber in the terahertz (THz)
region. The absorber comprises a Dirac semimetal film, a dielectric layer, and a gold ground …

In this paper, a double-band tunable perfect THz metamaterial absorber (MA) is proposed,
which includes a ring-shaped dielectric layer and a Dirac material layer. The simulated …

Two-dimensional materials such as graphene and black phosphorus have attracted
considerable attention owing to their peculiar properties and unique applications, serve also …

WTe2 is one of the wonder layered materials, displays interesting overlapping of electron–
hole pairs, opening of the surface bandgap, anisotropy in its crystal structure and very much …

Weyl semimetals are characterized by their bulk Weyl points—conical band touching points
that carry a topological monopole charge—and Fermi arc states that span between the Weyl …

We propose an asymmetric split-ring (ASR) structure based on Dirac semimetal, which has
Fano resonance with a high quality (Q) factor in the terahertz (THz) band, the Q factor can …

The advent of topological semi-metals with peculiar band structure and exotic quantum-
transport provides novel pathways for upgrading the performance of terahertz (THz) …

An ultra-narrowband terahertz (THz) perfect absorber with metal-insulator-metal (PA-MIM)
microstructures is presented. MIM microstructures is composed of Al disk on SiO 2/Al/Si …

This letter demonstrates the Dirac semimetal-platinum telluride (PtTe 2)-based terahertz
detector. The reported detector has a broadband response ranging from 0.1 to 1.5 THz at …

A terahertz plasmonic sensor based on parallel bulk Dirac semimetals (BDSs) is proposed
and numerically investigated in this paper. The physical origin of the sensor is induced by …
