4f-metal chlorides effect on electronic properties of carbon nanotubes

Abstract

In the present work, the channels of single-walled carbon nanotubes were filled with melts of ZnCl2, CdCl2, and TbCl3 by a capillary method with subsequent slow cooling. The detailed study of electronic structure of filled nanotubes was performed using Raman, optical absorption, and X-ray photoelectron spectroscopy. The obtained data are in mutual agreement and it proves that the filling of carbon nanotube channels with all these salts leads to the charge transfer from nanotube walls to the incorporated compounds, thus acceptor doping of nanotubes takes place. It was found out that encapsulated terbium chloride has the largest influence on the electronic properties of carbon nanotubes.

Electronic, structural and magnetic properties of Co2MnSn Alloy

“…The half-metallic ferromagnetic behavior was observed to have metallic behavior in one spin channel and energy gap (Eg) in the other channel that may lead to ~100% spin polarization [5]. Structural and magnetic properties of Co2-based full-Heusler alloy were investigated by In the present study the Co2MnSn Full Heusler alloy thin films were deposited on copper substrate using cost-effective electrodeposition technique.…”

Surface ion with Mo, Ti and Al for steel studies

“…In this case, various methods of surface modification are widely used. One of these methods is the ion implantation which offers not the application of an additional layer, but the introduction of ions directly into the surface layer [1][2][3][4][5]. In particular, it was shown in [1] that the implantation of molybdenum into ball-bearing steel leads to a decrease in the coefficient of friction.…”
