A note on the relation between discrete and resonance energies in quantum structures
A unified formula for energy levels in a quantum well is presented. It is shown that the formula can be used in evaluating resonances of a symmetric double-barrier structure in a wide range of barrier and well widths. A numerical example for GaAs/Al0.3Ga0.7As resonant double-barrier structure is presented to explain why the formula yields correct resonance energies even for narrow barriers, when the thickness of both barriers makes up 20%, of the well width.
