“…In addition to being small, carbon nanotubes (CNTs) are stable at high temperatures [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] and thus are of interest for many applications, including field emission tips, 10,14,15 nanoscale heaters, 22 and incandescent lights. 12,25 The temperatures T that CNTs reach have been inferred from the magnitude of their field emission current, 10 their breakdown temperature, 26 , the melting of nearby gold nanoparticles, 16 T -dependent Raman spectroscopy, 20,27 scanning thermal microscopy, 28 microfabricated Pt thermometers, 29 and their current-voltage response function.…”
