[en] A modified pulsed laser deposition process was used to enhance the nanostructure generation inside Bi₂Te₃ nanocrystals. In this process, an additional femotosecond laser beam was used to add an energy shock on the ablated flume, which can result in rich nanostructures embedded inside Bi₂Te₃ nanocrystals. A large Si wafer was used to 'freeze' such nanostructures and to effectively collect such nanostructured nanocrystals for further processing. The generated nanocrystals were studied by X-ray diffraction and scanning transmission electron microscopy, and the results prove the existence of such embedded nanostructures. Such nanocrystals were also characterized electrically and thermally for the conductivity measurements
