Photoionization cross section in a two-dimensional quantum ring: Aharonov–Bohm effect
چکیده انگلیسی


• The photoionization cross section (PCS) of a quantum ring is investigated.
• The PCS of quantum rings is strongly affected by the radius-to-width ratio.
• The PCS of a quantum ring may occur Aharonov–Bohm oscillation even in a finite width.

The photoionization cross section (PCS) associated with intersubband transitions in a two-dimensional quantum ring is investigated threaded by a magnetic flux. We model the quantum ring by a confining potential that can be continuously tuned from strictly one-dimensional to truly two-dimensional with finite radius-to-width ratio. Our results show that the PCS of a two-dimensional quantum ring decreases with increasing the width of the quantum ring. In addition, we found that the resonant peak of the PCS demonstrates the Aharonov–Bohm effect as a function of the magnetic flux.
