| Abstract | Freely suspended metallic single-walled carbon nanotubes (SWNTs) exhibit reduced current carrying ability compared to those lying on substrates, and striking negative differential conductance at low electric fields. Theoretical analysis reveals significant self-heating effects including electron scattering by hot nonequilibrium optical phonons. Electron transport characteristics under strong self-heating are exploited for the first time to probe the thermal conductivity of individual SWNTs (∼ 3600Wm-1K-1 at T=300K) up to ∼700K, and reveal a 1/T dependence expected for umklapp phonon scattering at high temperatures. © 2005 The American Physical Society. |
