Abstract
Ultrathin two-dimensional (2D) nanomaterials have attracted intense research efforts due to their extraordinary optoelectronic properties. However, the nucleation and growth mechanisms of 2D colloidal nanosheets are still poorly understood. Here, we follow the formation of ultrathin colloidal Cu2-xS nanosheets by in situ small-angle X-ray scattering. While thermal decomposition of copper-dodecanethiolates
