Free-Standing GeSi/Si Micro- and Nanotubes

Abstract

Micro- and nanotubes as well as free-standing flexible helical microcoils have been fabricated for the first time from strained Ge(x)Si(1-x)/Si bilayers. The scrolling process used for the formation of the nanoobjects proceed in a self-forming manner due to the action of interatomic forces inside the highly strained layers. The obtained tube diameter varied from 1.5 micrometers to 90 nanometers depending on the value of lattice mismatch and on the thickness of GeSi/Si bilayer.
