Non-lithographic formation of three dimensional periodic nanostructures by germanium nanowire etching.
نویسندگان
چکیده
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.

متن کاملSub-100 nm Si nanowire and nano-sheet array formation by MacEtch using a non-lithographic InAs nanowire mask.
We report a non-lithographical method for the fabrication of ultra-thin silicon (Si) nanowire (NW) and nano-sheet arrays through metal-assisted-chemical-etching (MacEtch) with gold (Au). The mask used for metal patterning is a vertical InAs NW array grown on a Si substrate via catalyst-free, strain-induced, one-dimensional heteroepitaxy. Depending on the Au evaporation angle, the shape and size...
متن کاملControllable doping and wrap-around contacts to electrolessly etched silicon nanowire arrays.
Top-down electroless chemical etching enables non-lithographic patterning of wafer-scale nanostructured arrays, but the etching on highly doped wafers produces porous structures. The lack of defect-free nanostructures at desired doping and the difficulties in forming reliable electrical side-contacts to the nanostructure arrays limits their integration into high performance nanoelectronics. We ...

We report a low-cost and simple method for fabrication of nonspherical colloidal lithographic nanopatterns with a long-range order by preheating and oxygen reactive ion etching of monolayer and double-layer polystyrene spheres. This strategy allows excellent control of size and morphology of the colloidal particles and expands the applications of the colloidal patterns as templates for preparin...
متن کاملControllable synthesis of branched ZnO/Si nanowire arrays with hierarchical structure
A rational approach for creating branched ZnO/Si nanowire arrays with hierarchical structure was developed based on a combination of three simple and cost-effective synthesis pathways. The crucial procedure included growth of crystalline Si nanowire arrays as backbones by chemical etching of Si substrates, deposition of ZnO thin film as a seed layer by magnetron sputtering, and fabrication of Z...
