Key crystallographic aspects of Ge nanowires grown in a supercritical fluid were investigated by high‐resolution transmission electron microscopy. The favored <110> growth direction was attributed to the crystallographic faceting of low‐energy {111} and {100} planes on the initial nucleus crystal and the exposed nanowire sidewall surfaces. Electron diffraction patterns of individual nanowires exhibited forbidden 1/3 {422} reflections due to incomplete {111} surface facets and the finite size of the nanowires.
