Abstract
We present calculations of the resonant-tunneling current through low-energy states (sharp resonances) confined in quantum-box nanostructures. We determine how the fine structure in the current provides a spectroscopy for these box states. Resonant tunneling produces fine structure when the box states are resonant with the emitter Fermi level. The results agree qualitatively with the observations of Reed et al.Keywords
