We propose a multi-mode surface plasmon resonance absorber based on dart-type single-layer graphene, it has advantages of polarization independence, tunability and high sensitivity. Four modes of polarization-independent perfect absorption are achieved at 3000–5000 nm.

Terahertz functional devices have been instrumental in the development of terahertz technology. And the advent of metamaterials has greatly contributed to the advancement of terahertz devices. However, most of today's...

We present a novel, structurally simple, multifunctional broadband absorber. It consists of a patterned vanadium dioxide film and a metal plate spaced by a dielectric layer. The temperature control allows...

In this work, we demonstrate that the performance of c-Si/ZnO heterojunction ultrathin-film solar cells (SCs) is enhanced by an integrated structure of c-Si trapezoidal pyramids on the top of c-Si...

We proposed a four-band terahertz tunable narrow-band perfect absorber based on bulk Dirac semi-metallic (BDS) metamaterials with microstructure. The resonance frequency of the absorber can be adjusted by adjusting the Fermi level of BDS.
