“…Ion irradiation has been used extensively to tune the mechanical [1][2][3], optical [4][5][6], electrical [4,6,7], and chemical [8,9] properties of materials, as well as for nanofabrication [6,8,[10][11][12]. Understanding the response of materials to ion irradiation is especially important for the design of engineering materials, such as radiation-tolerant materials for nuclear reactors [3,[13][14][15], for ion implantation in semiconductors and for nanofabrication.…”

Targeted irradiation of nanostructures by a finely focused ion beam provides routes to improved control of material modification and understanding of the physics of interactions between ion beams and nanomaterials. Here, we studied radiation damage in crystalline diamond and silicon nanostructures using a focused helium ion beam, with the former exhibiting extremely longrange ion propagation and large plastic deformation in a process visibly analogous to blow forming. We report the dependence of damage morphology on material, geometry, and irradiation conditions (ion dose, ion energy, ion species, and location). We anticipate that our method and findings will not only improve the understanding of radiation damage in isolated nanostructures, but will also support the design of new engineering materials and devices for current and future applications in nanotechnology.
