Going straight : A simple and robust mechanism coherently directs nanowire growth directions by introducing a local temperature gradient as the local kinetic variable during the conventional vapor–liquid–solid (VLS) growth (see picture, scale bar=200 μm). The nanowires grow straight in the vertical direction, but possess kinks near the catalytic tips.
