Infrared Study of Charge Carrier Confinement in Doped (6,5) Carbon Nanotubes

Klaus H. Eckstein et al.

Summary: This study investigates the far/mid-infrared response of redox chemically doped semiconducting carbon nanotubes. Contrary to expectations, it is found that the Drude-type plasmon shifts to lower wavenumbers with increasing doping level. Monte Carlo simulations of the optical response attribute this behavior to the confinement of excess charge carriers at low doping levels and their progressive delocalization when approaching degenerate doping. The coupling of vibrational modes to intraband excitations in the doped semiconducting carbon nanotubes can be probed via a double-resonance process, shedding new light onto the character and coupling of electronic and vibrational degrees of freedom.

Quantifying charge carrier localization in chemically doped semiconducting polymers

Shawn A. Gregory et al.

Summary: A model is developed to describe the behavior of charge carriers in semiconducting polymers and quantify charge carrier localization and other transport parameters. By measuring temperature-dependent electrical conductivity, Seebeck coefficient, and extent of oxidation, a semi-localized transport (SLoT) model is developed to capture both localized and delocalized transport contributions. The SLoT model improves the ability to predict and tailor electronic properties of doped semiconducting polymers.

High-performance carbon nanotube electronic ratchets

Ji Hao et al.

Summary: The advancements in low-power portable/wearable electronic devices require technologies that can provide power without bulky battery storage. Electronic ratchets, such as conjugated polymer-based and semiconducting single-walled carbon nanotube (s-SWCNT) channels, have been proposed as solutions to convert AC signals or electronic noise into stable DC power. These s-SWCNT electronic ratchets demonstrate higher output power and improved stability compared to polymer-based analogs, showing promise as energy harvesting devices for portable, low-power applications.
