Chemistry of Materials: Impurity controlled crystal growth in low dimensional bismuth telluride

Impurity controlled crystal growth in low dimensional bismuth telluride Sharifi, T., Yazdi, S., Costin, G., Apte, A., Coulter, G., Tiwary, C., and Ajayan, P.M. Chemistry of Materials,  https://pubs.acs.org/doi/10.1021/acs.chemmater.8b02548 ABSTRACT Topological insulators, such as layered Bi2Te3, exhibit extraordinary properties, manifesting profoundly only at nanoscale thicknesses. However, it has been challenging to synthesize these structures with controlled thickness. […]
