Larger NCs show similarity with the bulk in layered arrangement of copper and chalcogen atoms. Middle sized NCs show characteristics of both. Smaller and middle sized NCs are known for copper sulfides and all the three category are reported for the copper selenides.

September 19, 2018 - Two-dimensional (2D) semiconductors with suitable direct band gaps, high carrier mobility, and excellent open-air stability are especially desirable for material applications. Herein, we show theoretical evidence of a new phase of a copper(I) sulfide (Cu2S) monolayer, denoted δ-Cu2S, with both novel electronic properties and superior oxidation resistance.
