Ab initio study of uniaxial strain-induced thermoelectric property tuning of individual single-wall carbon nanotubes

Abstract

Carbon nanotubes (CNT) have garnered significant importance as thermoelectric (TE) material due to their high TE performance owing to their inherent fascinating one-dimensional quantum confinement of charge carriers. Among various...

Thermoelectric property enhancement of single-wall carbon nanotube network by ICl intercalation and filling: a first-principles study

“…However, bipolar transport due to carrier generation at elevated temperatures is supposed to increase in such a way that the value of S would decrease more and is expected to cause a sign reversal of S . 34 We calculated the Seebeck coefficient beyond 1000 K, particularly for the C1 doping configuration. Indeed, the effect of bipolar transport was more noticeable and resulted in a considerable decrease of S with even sign reversal beyond 1650 K, as observed in Fig.…”
