Optical links are moving to higher and higher transmission speeds while shrinking to shorter
and shorter ranges where optical links are envisaged even at the chip scale. The scaling in …

Graphene, in its ideal form, is a two-dimensional (2D) material consisting of a single layer of
carbon atoms arranged in a hexagonal lattice. The richness in morphological, physical …

We present an overview of the main techniques for production and processing of graphene
and related materials (GRMs), as well as the key characterization procedures. We adopt …

Layered two-dimensional (2D) semiconductors, such as MoS2 and SnS2, have been
receiving intensive attention due to their technological importance for the next-generation …

We present a simple dual band absorber design and investigate it in the terahertz (THz)
region. The proposed absorber works in dual operating bands at 5.1 THz and 11.7 THz. By …

The realization that nanostructured graphene featuring nanoscale width can confine
electrons to open its bandgap has aroused scientists' attention to the regulation of graphene …

In this paper, a perfect metamaterial (MTM) absorber with simple design has been proposed
and investigated in terahertz (THz) region. The suggested absorber has the controllability of …

Graphene, a single atomic layer of graphite, has been the focus of recent intensive studies
due to its novel electronic and structural properties. Metals grown on graphene also have …

In this paper, we propose a dual-band tunable absorber with a graphene-dielectric-metal
structure as a sensor in the terahertz (THz) region. The finite element method (FEM) based …

Abstract Graphene/Si Schottky junction solar cells are widely studied in relation to the
harvesting of solar energy, but high efficiency is limited due to surface recombination at the …
