Abstract
Due to producing both metallic and semiconducting carbon nanotubes simultaneously during growth procedure, it is probably needed to separate them after synthesize. In this article a novel and efficient method for separating metallic single-walled carbon nanotubes from semiconducting is proposed. This method is based on magnetic properties of carbon nanotubes and takes advantages of an electromagnet in order to apply magnetic field on carbon nanotubes. In this work, carbon nanotubes are utilized in the solid phase. Results are discussed by analyzing field emission scanning electron microscopy images, X-ray diffraction, and Raman spectroscopy diagrams and also by measuring the resistivity of samples.
