Figure 2

(a) Shows a computed temperature profile of our W-PC sample under heating. The silicon substrate is kept at T = 600K. (b) shows a computed temperature profile of our heated W-PC when a piece of black-CNT is coated at the center region of its DBR top surface. The silicon substrate is kept at T = 600K. (c) shows the computed temperature along the dashed line of the silicon top surface. The filament’s input powers are Pinput = 4, 5, 6, 7 and 8W, respectively. Inset: A computed temperature distribution profile of the silicon substrate at Pinput = 4 Watts. (The computation is performed using COMSOL version 5.4 software.
