Excitons in a cylindrical GaAs Pöschl-Teller quantum dot

The exciton binding energy in a cylindrical quantum dot (QD) with Pöschl–Teller confining potential is studied with the use of the effective mass approximation and a variational calculation procedure. A GaAs prototype structure is particularly considered and both the spatially‐direct (DE) and spatia...
