Visualising discrete structural transformations in germanium nanowires during ion beam irradiation and subsequent annealing.
In this article we detail the application of electron microscopy to visualise discrete structural transitions incurring in single crystalline Ge nanowires upon Ga-ion irradiation and subsequent thermal annealing. Sequences of images for nanowires of varying diameters subjected to an incremental increase of the Ga-ion dose were obtained. Intricate transformations dictated by a nanowire's geometr...
متن کاملCoupling of Semiconductor Nanowires with Neurons and Their Interfacial Structure
We report on the compatibility of various nanowires with hippocampal neurons and the structural study of the neuron-nanowire interface. Si, Ge, SiGe, and GaN nanowires are compatible with hippocampal neurons due to their native oxide, but ZnO nanowires are toxic to neuron due to a release of Zn ion. The interfaces of fixed Si nanowire and hippocampal neuron, cross-sectional samples, were prepar...
متن کاملNanoscale surface pattern formation kinetics on germanium irradiated by Kr+ ions
Nanoscale surface topography evolution on Ge surfaces irradiated by 1 keV Kr+ ions is examined in both directions perpendicular and parallel to the projection of the ion beam on the surface. Grazing incidence small angle x-ray scattering is used to measure in situ the evolution of surface morphology via the linear dispersion relation. A transition from smoothing (stability) to pattern-forming i...
متن کاملResistive switching memory characteristics of Ge/GeOx nanowires and evidence of oxygen ion migration
The resistive switching memory of Ge nanowires (NWs) in an IrOx/Al2O3/Ge NWs/SiO2/p-Si structure is investigated. Ge NWs with an average diameter of approximately 100 nm are grown by the vapor-liquid-solid technique. The core-shell structure of the Ge/GeOx NWs is confirmed by both scanning electron microscopy and high-resolution transmission electron microscopy. Defects in the Ge/GeOx NWs are o...
متن کاملModification of the optical and structural properties of ZnO nanowires by low-energy Ar+ ion sputtering
The effects of low-energy (≤2 kV) Ar+ irradiation on the optical and structural properties of zinc oxide (ZnO) nanowires (NWs) grown by a simple and cost-effective low-temperature technique were investigated. Both photoluminescence spectra from ZnO NW-coated films and cathodoluminescence analysis of individual ZnO NWs demonstrated obvious evidences of ultraviolet/visible luminescent enhancement...
