Calculate the transmission coefficient of tunneling effect

Please login with a confirmed email address before reporting spam

I read an article titled "Learning the Quantum Mechanics Concepts of Double Barrier Structures", which focuses on the fourth study: the stationary study of calculating transmission and reflection coefficients. https://cn.comsol.com/blogs/learning-quantum-mechanics-concepts-with-double-barrier-structures/#goto-comments There is a formula for calculating projection coefficients using comsol, abs (schr. open1. int (psi)/psi0) ^ 2. Can you help me explain the meaning of this formula.
