A 12-nm diameter nanowire is grown on a silicon carbide surface maintained at a temperature 2400 K. The silicon carbide nanowire is surrounded by gas at a temperature

∞

8000 K with a convective coefficient 1.25 x 105 W/m2·K. The nanowire stops growing when the length of the wire reaches 500 nm. What is the tip temperature when the wire length is 500 nm, in K? The properties for silicon carbide can be estimated at 1500 K.
