At the ultimate thinness level, electrons in two-dimensional van der Waals field-effect transistors (FETs) are particularly vulnerable to interactions with the surrounding environment, leading to strong fluctuations of the current output.
Since the early experimental efforts towards the generation and characterisation of Majorana zero modes in solid state devices, remarkable progress has been accomplished. Recently, this field has seen a revival thanks to new experiments of exceptional quality on proximitised semiconducting nanowires.

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 unwanted interlayer adsorbates.

Advances in solar cell technologies are rapidly changing the landscape of global energy supply. Conversion efficiencies are however ultimately limited to a maximum ~40% in conventional silicon-based solar cell designs.
We report isolation of antimonene, a new allotrope of antimony that consists on a single layer of atoms. Graphene is well-known by its tremendous potential applications; however the lack of electronic gap limits its use in the electronics technology.
