Fig. 1From: Scalability of the Heat and Current Treatment on SWCNTs to Improve their Crystallinity and Thermal and Electrical ConductivitiesPlot of electrical and thermal conductivities after treatment as a function of (a) applied current density at 750 °C and (b) applied treatment temperature at 150 A cm−2. c Current density and temperature as functions of layer number (SWCNT amount, one layer = ~3 mg). d TEM images for untreated and treated (one, four, eight layers) SWCNTs and (e) Raman spectra for the untreated and treated SWCNTs at their respective optimum treatment conditionsBack to article page
