Question

A particle strikes a potential barrier of height U and width L. Derive an expression for

the approximate transmission probability, if the energy of the particle E < U​

Answer 1

Explanation:

Quantum tunneling is a phenomenon in which particles penetrate a potential energy barrier with a height greater than the total energy of the particles. The phenomenon is interesting and important because it violates the principles of classical mechanics. Quantum tunneling is important in models of the Sun and has a wide range of applications, such as the scanning tunneling microscope and the tunnel diode.
