The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

Interactions induced by electromagnetic fluctuations, such as van der Waals and Casimir
forces, are of universal nature present at any length scale between any types of systems …

Semi-metallic graphene and semiconducting monolayer transition-metal dichalcogenides
are the most intensively studied two-dimensional materials of recent years,. Lately, black …

Transition metal dichalcogenides in the class MX 2 (M= Mo, W; X= S, Se) have been
identified as direct-gap semiconductors in the monolayer limit. Here, we examine light …

Light emission in two-dimensional (2D) transition metal dichalcogenides (TMDs) changes
significantly with the number of layers and stacking sequence. While the electronic structure …

Fluorescent carbon nanomaterials have broadly useful chemical and photophysical
attributes that are conducive to applications in biology. In this review, we focus on materials …

Raman spectroscopy is the inelastic scattering of light by matter. Being highly sensitive to
the physical and chemical properties of materials, as well as to environmental effects that …

Semiconducting carbon nanotubes promise a broad range of potential applications in
optoelectronics and imaging, but their photon-conversion efficiency is relatively low …

This article reviews the electronic and transport properties of carbon nanotubes. The focus is
mainly theoretical, but when appropriate the relation with experimental results is mentioned …

Carbon nanotubes (CNTs) are nearly ideal one-dimensional (1D) systems, with diameters of
only 1–3 nm and lengths that can be on the scale of centimetres. Depending on the …
