摘要: This paper presents an analysis of the local electric field in the hexagonal boron nitride (h-BN) by introducing a modified parameter. Based on the determination of the modified parameter of h-BN, the revised Lorenz equation is developed. Then, the permittivity at high temperature and in the microwave frequency is investigated. In addition, this equation is derived for evaluating the temperature coefficient of the permittivity of h-BN. The analyses show that the permittivity increases with the increasing temperature, which is mainly attributed to the positive temperature coefficient of the ionic polarizability.
