The intrinsic reactivity of curved nanoscale germanium surfaces, under carefully controlled anodic etch conditions, is exploited to produce intricate three-dimensional helical patterns. Such structures, retaining crystalline Ge character and yielding strong visible emission, demonstrate a feature spacing of a periodic nature that correlates with their measured width.
