Controlled fabrication and maneuvering of nanostructures has been of great interest in nanotechnology because of the potential applications it could deliver. In this study, we demonstrate the in situ fabrication and manipulation method of nanopillars made of a Pt-C composite by means of electron induced bending. Hereafter, we propose novel experiments contributing to unfold the mechanisms responsible for the bending process. Our results confirm that this bending is due to the phase transformation of the as-grown Pt-C nanopillars induced by the electron beam irradiation. The optimized beam energy and the beam irradiation dose necessary for the bending have been experimentally determined and corroborated by Monte Carlo simulations. The results further advance the understanding of electron matter interaction and pave the way for designing 3D nanostructures for various applications.Controlled fabrication and maneuvering of nanostructures has been of great interest in nanotechnology because of the potential applications it could deliver.
