Abstract

In 2D materials devices, understanding interfacial reactions in the formation of metal contacts is important for tuning their properties. Here, electron microscopy reveals the formation of an intermetallic contact layer, characterized by an efficient edge-type charge transfer, when nickel, chromium, or titanium is deposited onto black-arsenic films.
