Si–Cu alloy nanowires grown by oblique angle deposition as a stable negative electrode for Li-ion batteries

Thin films having nanocolumnar arrays made of various Si–Cu atomic ratios (90–10, 80–20, 70–30 %) are fabricated by an ion-assisted oblique angle co-deposition technique to produce stable negative electrodes for lithium-ion batteries. Cu is added into the electrode because of its ductility and elect...
