Many envisaged applications, such as nanoelectronics, photovoltaics, thermoelectric power generation, light-emission devices, energy storage and biomedicine, necessitate single-walled carbon nanotube (SWCNT) samples with specific uniform electronic properties. The precise investigation of the electronic properties of filled SWCNTs on a qualitative and quantitative level is conducted by optical absorption spectroscopy, Raman spectroscopy, photoemission spectroscopy and X-ray absorption spectroscopy. This review is dedicated to the description of the spectroscopic methods for the analysis of the electronic properties of filled SWCNTs. The basic principle and main features of SWCNTs as well as signatures of doping-induced modifications of the spectra of filled SWCNTs are discussed.

And Chemical Properties

Single-walled carbon nanotubes (SWCNTs), which possess electrical and thermal conductivity, mechanical strength, and flexibility, and are ultra-light weight, are an outstanding material for applications in nanoelectronics, photovoltaics, thermoelectric power generation, light emission, electrochemical energy storage, catalysis, sensors, spintronics, magnetic recording, and biomedicine. Applications of SWCNTs require nanotube samples with precisely controlled and customized electronic properties. The filling of SWCNTs is a promising approach in the fine-tuning of their electronic properties because a large variety of substances with appropriate physical and chemical properties can be introduced inside SWCNTs. The encapsulation of electron donor or acceptor substances inside SWCNTs opens the way for the Fermi-level engineering of SWCNTs for specific applications. This paper reviews the recent progress in applications of filled SWCNTs and highlights challenges that exist in the field.

We investigate electrical properties of mono- and bilayer single-walled carbon nanotube (SWCNT) films located on silicon oxide substrates. The substrate is a silicon dioxide crystal film characterized by a P42/mnm space group with (100) surface. The single-walled carbon nanotubes are armchair nanotubes of subnanometer diameter (4,4) and nanometer diameter (7,7). It is found that the diameter of the nanotubes is of great importance and determines the electronic properties of the film on the substrate in a large degree. Thin tubes (4,4) formed in a bilayer film (with a reciprocally perpendicular orientation relative to each other) have the least resistance. The substrate has insignificant influence on the electronic properties of such a film. Films with larger diameter tubes are characterized by a higher resistance value. It is found that the important role is played by the contact surface of the SWCNT–substrate.
