Abstract

This project paper mainly focuses on the physical models and the current characteristics of charge density waves (CDW) in the niobium triselenide (NbSe\(_{3}\)) with anisotropic band structures. The models discussed in this paper are classical single particle transport model (a.k.a. sliding model) and quantum tunneling model. The classical model gives a threshold electric field beyond which the CDW material is a conductor. Finally, CDW effects could be modulated by applying gate voltage, resulting in field-effect CDW transistors.
