Research Abstract

Carbon nanotubes are well known for its long electron mean free path. In this research, a periodical magnetic field is applied vertical to the carbon nanotube. The possibilities of creation of coherent microwaves or light due to the interactions between electrons and the periodical magnetic field have been investigated. The fundamental of this research are aligning carbon nanotubes between the electrode and suitable design of periodical magnetic field. An easy process has been developed to align carbon nanotubes between the electrodes. Furthermore, exchange coupling between soft and hard magnetic thin film was used to creating strip domains between the electrodes. Due to the large resistance between the electrode and carbon nanotubes, coherent light could not be observed in the experiment. Future works will focus onto the minimization of the resistance between the electrode and carbon nanotubes.
