The effective redirection of spin waves and their local control are among the main challenges faced by the emergent field of magnon spintronics. To solve the problem Lara et al. introduce a breakthrough technology for communication and signal processing using spin waves localized at the edges of magnetic nanostructures.

This tutorial review presents an overview of the basic theoretical aspects of two-dimensional (2D) crystals. We revise essential aspects of graphene and the new families of semiconducting 2D materials, like transition metal dichalcogenides or black phosphorus.

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.
