Exciton states in three-dimensional ring structures—a differential-geometric analysis
Exciton states in three-dimensional ring structures—a differential-geometric analysis
An effective method for computing excitonic shifts in curved quantum‐wire geometries is presented. As a case example, we consider a GaAs quantum ring with infinite barriers along the cross‐sectional dimensions assumed to be of square shape albeit this assumption can be easily avoided. A simple analytic expression for excitonic shifts …
