Outline of Final Research Achievements |
Normally electrons is solids travel with a speed which is much less than the velocity of light. However, we need a relativistic equation of motion for the description of the electrons in an organic conductor alpha-(BEDT-TTF)2I3 under high pressure. The characteristic effect of the so-called Dirac fermions is observed in the transport phenomena under magnetic field. In this study we studied the transport phenomena under magnetic field in the organic conductor alpha-(BEDT-TTF)2I3 theoretically by including the interaction effect and obtained the results that are in good agreement with the experiments.
