The quantum tunnelling effect in double barrier structure

Abstract

The purpose of this paper is to study the quantum tunnelling effect of double barriers. At the beginning, the research background and application of quantum tunnelling effect are described, and then the research purpose is explained. Although the real double barriers are very complex, most of them are composed of double barrier, double triangle barrier and double parabola barrier. The author mainly studies the barrier of double parabola. The reason is that the quantum tunnelling effect proposed by Hund will greatly adjust the internal structure of triangular conical molecules, which has great research significance. In triangular conical molecules, the change of potential energy of a single atom with its position may be very complicated, but the part that can occur with the consequential effect is similar to the potential barrier of a double parabola. In this paper, the wave function, projection and reflection coefficients of the biparabolic barrier tunnelling effect are analysed to determine whether it has a great adjustment effect on triangular conical molecules.
