Photoelectrochemical modulation of neuronal activity with free-standing coaxial silicon nanowires
Nature Nanotechnology, 2018 Optical methods for modulating cellular behaviour are promising for both fundamental and clinical applications. However, most available methods are either mechanically invasive, require genetic manipulation of target cells or cannot provide subcellular ...

Growth of silicon self-assembled nanowires by using gold-enhanced CVD technology
Semiconductor Physics, Quantum Electronics & Optoelectronics, 2018 In spite of the fact that, a great deal of experimental research has been published, there is a lack of good understanding of silicon nanowires growth to exert control over important properties of the system, though it presents the simplest system like ...

Ballistic thermal transport in silicon nanowires
Scientific Reports, 2017 We have experimentally investigated the impact of dimensions and temperature on the thermal conductivity of silicon nanowires fabricated using a top-down approach. Both the width and temperature dependences of thermal conductivity agree with those in the

Silicon Nanowire Band Gap Modification [PDF]
Nano Letters, 2006 Band gap modification for small-diameter (1 nm) silicon nanowires resulting from the use of different species for surface termination is investigated by density functional theory calculations. Because of quantum confinement, small-diameter wires exhibit a direct band gap that increases as the wire diameter narrows, irrespective of surface termination ...
