Free-standing metallic nanostructures are considered to be highly relevant to many branches of science and technology with
applications of three dimensional metallic nanostructures ranging from optical reflectors, actuators, and antenna, to
free-standing electrodes, mechanical, optical, and electrical resonators and sensors. Strain-induced out-of-plane fabrication has
emerged as an effective method which uses relaxation of strain-mismatched materials. In this work, we report a study of the
thermal annealing-induced shape modification of free-standing nanostructures, which was achieved by posi-
