(a) Calculated surface temperature rise of the device shown in Fig. 1(a) when a current passes through the heater line. The dimension of the thermal image is wide and long. Point E in Fig. 1(b) is located at below the top edge and from the right edge. (b) Temperature rise along the thermometer line. Point E in Fig. 1(b) is located at . (c) Temperature rise along the nanowire. Points E and J in Fig. 1(b) are located at 0 and , respectively.

The measurement results of Seebeck coefficient of the InSb nanowire as a function of temperature . The filled circles are the as-measured data and the upper bounds of the error bars are the corrected ones based on the temperature measurement error estimated by the thermal simulation. The calculation results based on the 1D MB (black line) and 3D (gray line) DOS were made to fit with the as-measured data by adjusting the corresponding Fermi energy values at different temperatures, and cannot be distinguished from each other in many areas of the plot.
