In this work, a theoretical study is presented on the combined effects of an external electric field and a nonresonant intense laser field on the electronic properties of a quantum dot (QD) with a truncated cone shape. This QD was made from a type-II CdTe/CdSe heterostructure (core/shell). Using the effective mass approximation with parabolic bands and the finite element method, the Schrödinger equation was solved to analyze the confined states of the electron, hole, and exciton. The study demonstrates the potential for combining nonresonant intense laser and electric fields to control confinement properties in semiconductor nanodevices, with potential applications in optoelectronics and quantum mechanics-related technologies.
