Figure 1.

The experimental configuration and schematic show of heat flow. a is the TEM image of the whole device, where we can see the nanowire is suspended on the hole of a porous carbon film. It was directly taken from the phosphorus screen by a digital video machine when the system was heated to 350 °C. b shows the schematic heat flow marked by the arrows
