      abstract     = {Once nanomaterials have been synthesized, inducing further
                      structural modifications is challenging. However, being able
                      to do so in a controlled manner is crucial. In this context,
                      germanium nanowires are irradiated in situ within a
                      transmission electron microscope (TEM) by a 300 keV xenon
                      ion beam at temperatures ranging from room temperature (RT)
                      to 500 °C. The ion irradiation is performed in situ and the
                      evolution of nanowires during irradiation is monitored. At
                      300 °C and below, where the temperature is low enough to
                      allow amorphization, the ion beam causes the formation of
                      nanostructures within the nanowires. Formation of nanopores
                      and swelling of nanowires is observed for a very low fluence
                      of 2.2 × 1014 and up to 4.2 × 1015 ions cm−2. At higher
                      fluences, the thickness of the nanowires decreases, the
                      nanowires lose their wire-like cylindrical shape and the
                      nanostructuring caused by the ion beam becomes more complex.
                      The nanostructures are observed to be stable upon
                      crystallization when the nanowires are annealed at 530 °C.
                      Furthermore, in situ imaging allows the growth of nanopores
                      during irradiation to be followed at RT and at 300 °C
                      providing valuable insights into the mechanism responsible
                      for the nanostructuring.},
