Light Generation and Harvesting in a van der Waals Heterostructure

Two-dimensional (2D) materials are a new type of materials under intense study because of their interesting physical properties and wide range of potential applications from nanoelectronics to sensing and photonics. Monolayers of semiconducting transition metal dichalcogenides MoS2 or WSe2 have been proposed as promising channel materials for field-effect transistors. Their high mechanical flex...

Tunable Electronic Properties in van der Waals Heterostructure Germanene/Germanane

It is challenging to epitaxially grow germanene on conventional semiconductor substrate. Based on first-principles calculations, we investigate the structural and electronic properties of germanene/germanane heterostructure (HTS). The results indicate that the Dirac cone with nearly linear band dispersion of germanene maintains in the band gap of substrate. Remarkably, the band gap opened in th...

Franckeite as a naturally occurring van der Waals heterostructure

The fabrication of van der Waals heterostructures, artificial materials assembled by individual stacking of 2D layers, is among the most promising directions in 2D materials research. Until now, the most widespread approach to stack 2D layers relies on deterministic placement methods, which are cumbersome and tend to suffer from poor control over the lattice orientations and the presence of unw...

Nanocavity Integrated van der Waals Heterostructure Light-Emitting Tunneling Diode.

Developing a nanoscale, integrable, and electrically pumped single mode light source is an essential step toward on-chip optical information technologies and sensors. Here, we demonstrate nanocavity enhanced electroluminescence in van der Waals heterostructures (vdWhs) at room temperature. The vertically assembled light-emitting device uses graphene/boron nitride as top and bottom tunneling con...
