Description
Summary:Rao and Zhang reply to the question by Rubin and Chen on how would the picture change if Sc were deposited in a discontinuous layer rather than dispersed throughout the SbTe film. Scandium atoms were deposited randomly throughout the antimony telluride (Sb2Te3) thin film to serve as robust crystalline precursors for speeding up the intrinsic incubation of stable nuclei. If Sc atoms were deposited into discontinuous layers, potentially forming Sc2Te3, those layers may serve as a robust two-dimensional template to trigger rapid crystal growth.
