Defects in two-dimensional (2D) transition metal dichalcogenides (TMDs) have properties that are useful for optoelectronics, (1) sensing, (2) and electro/photocatalysis. (3,4) These properties are related to defect-induced in-gap states that modify the electronic structure of the host crystal. The in-gap states can trap excitons and give rise to defect-mediated photoluminescence (PL) (5,6) and even single-photon emission.

AbstractGraphene-based spintronic devices require efficient spin injection, and dielectric tunnel barriers are typically used to facilitate spin injection. However, the direct growth of ultrathin dielectrics on two-dimensional surfaces is challenging and unreliable. Here we report spin injection in graphene lateral spin valves using ferromagnetic van der Waals contacts of indium and cobalt (In–Co), and without the deposition of dielectric tunnel barriers.

Developing nations face escalating loss and damage from extreme weather and from slow onset events such as melting glaciers, desertification and sea level rise. Loss and damage due to climate change could cost the global economy $19-$59 trillion a year by 2049, suggests recent research. Loss and damage funding is in addition to the climate finance needed by developing countries for mitigation.
