Si/SiGe bilayers of 18 nm thickness have been rolled into tubes of 1.3 μm diameter. Tubes of 60 μm length have been detached from the substrate and placed between a nanorobotic manipulaltor and an AFM tip to analyse their mechanical properties using the Euler buckling method. The tubes proved to be mechanical robust with a flexural rigidity (EI) amounting to 4.1*10-15 Nm2. The presented manipulation technique has been proven to be a suitable approach to characterize the mechanical properties of these self-scrolled semiconductor structures. The results give insights into the suitability of these structures for micromechanical devices. | | ISBN: | 0-9767985-6-5 |
