Here, we show successful filling of 1.4 nm singlewalled carbon nanotubes (SWNT) with PbTe nanocrystals. The structure of one-dimensional PbTe in SWNT was determined using highresolution transmission electron microscopy (HRTEM). The electronic structure of composites was studied by optical absorbance and Raman spectroscopies indicating no noticeable interaction of encapsulated PbTe with SWNT wall. Experimental data are supported by ab-initio calculations, showing non-zero density of states at the Fermi level of PbTe@SWNT(10,10) provided by both SWNT and PbTe states and thus metallic conductivity of the composite.
Keywords:
encapsulated SWNT, SWCNT, quasi free-standing nanocrystals, PbTe@SWCNT, doping, electronicproperties, HAADF STEM.
