- Abstract
Layered intergrowth compounds in the homologous PbmBi2nTe3n+m family are interesting because they are examples of natural heterostructures. We present a simple solution-based synthesis of two-dimensional nanosheets of PbBi2Teɸ, Pb2Bi2Te5, and PbBi6Te10 layered intergrowth compounds, which are members of the PbmBi2nTe3n+m [that is, (PbTe)m-(Bi2Te3)n] homologous series. Few-layer nanosheets exhibit narrow optical band gaps (0.25-0.7 eV) with semiconducting electronic-transport properties.
