In this study, the electronic structure of the ground states of a quantum dot structure with spherical well was investigated. The ground state energy depending on dot radius and stoichiometric ratio was calculated for GaAs/AlxGa1-x As quantum structure including hydrogenlike impurity on center. Wave function was constructed in terms of Slater type basis functions and it was obtained by using Quantum Genetic Algorithm (KGA) method and the ground state energy was calculated by Hartree-Fock-Roothaan (HFR) method.

Bu çalışmada sonlu küresel kuyudaki kuantum nokta yapısının taban durum elektronik özellikleri incelendi. Merkezinde hidrojen benzeri safsızlık olan GaAs/Alx Ga1-x As kuantum nokta yapısının farklı kuantum nokta yarıçapları için taban durum enerjileri nokta yarıçapına ve katkılanma oranına bağlı olarak hesaplandı. Slater tipi baz fonksiyonları cinsinden oluşturulan dalga fonksiyonu Kuantum Genetik Algotirma (KGA) yöntemi kullanılarak elde edildi ve Hartree-Fock-Roothaan (HFR) yöntemi ile taban durumu enerjisi hesaplandı.
