We present the science and technology roadmap for graphene, related two-dimensional
crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts …

The occurrence of charge-density waves in three selected layered transition-metal
dichalcogenides—1T-TaS 2, 2H-TaSe 2 and 1T-TiSe 2—is discussed from an …

The concept of a charge density wave (CDW) permeates much of condensed matter physics
and chemistry. CDWs have their origin rooted in the instability of a one-dimensional system …

We report inelastic x-ray scattering measurements of the temperature dependence of
phonon dispersion in the prototypical charge-density-wave (CDW) compound 2 H-NbSe 2 …

Using first-principles calculations we show that the band gap of bilayer sheets of
semiconducting transition-metal dichalcogenides (TMDs) can be reduced smoothly by …

The quantum coupling of fully different degrees of freedom is a challenging path towards
new functionalities for quantum electronics,,. Here we show that the localized classical spin …

Since the successful isolation of single‐layer graphene with an atomic thickness, various
van der Waals (vdW) materials have been intensively studied owing to their unique …

Strong electron correlations are at the heart of many physical phenomena of current interest
to the condensed matter community. Here we present a survey of the mechanisms …

Charge density wave (CDW) is an important concept in condensed matter physics, germane
to a number of physical phenomena. But the origin of CDW is still under debate, partly …

We investigate the charge-density wave (CDW) instability in single and double layers, as
well as in the bulk 2 H-NbSe 2. We demonstrate that the density functional theory correctly …
