Three-dimensional modeling of the relationship between static tunneling and the optical absorption coefficient in tunnel diodes

This article investigates the Franz–Keldysh effect and the tunneling processes observed in tunnel diodes. The relationship between the optical absorption coefficient and the tunneling probability is analyzed using both theoretical and graphical methods. The dependence of both processes on energy is illustrated through 3D graphs. The surfaces defined according to the energy level distribution may contribute to improving the efficiency of optoelectronic devices based on tunnel diodes.
