TLDR
In this paper, it was shown that spin polarization can also be achieved without the need for magnetism by using the unique crystal symmetry of tungsten selenide, which creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.Abstract:
A magnetic field can lift the spin degeneracy of electrons. This Zeeman effect is an important route to generating the spin polarization required for spintronics. It is now shown that such polarization can also be achieved without the need for magnetism. The unique crystal symmetry of tungsten selenide creates a Zeeman-like effect when a monolayer of the material is exposed to an external electric field.read more

Atomic-Scale Probing of Reversible Li Migration in 1T-V1+ xSe2 and the Interactions between Interstitial V and Li.

TL;DR: It is found that lithium ion migration destroys the cationic orderings and leads to a phase transition from superstructure to nonsuperstructure that is reversible, that is, the superstructure returns back after extraction of lithium ion from Li yV1+ xSe2.

Quantum Transport Detected by Strong Proximity Interaction at a Graphene–WS2 van der Waals Interface
TL;DR: Graphene couples to quantum localization processes in WS2 via the Coulomb interaction and results in the observed signatures of quantum transport, showing that theoretical descriptions of the van der Waals interface should not ignore localized strong correlations.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
