Abstract

In GaAs / Ga1-xAlxAs spherical quantum dot, the effect of the dielectric constant, which is a function of hydrostatic pressure, on 2p excited state binding energy and impurity self-polarization, was calculated using the variation method as a function of the dot radius and pressure. According to the results obtained, the dielectric constant and hydrostatic pressure have been shown to change the 2p excited state binding energy and impurity self-polarization. The variations of impurity self-polarization and binding energy depending on dot radius, hydrostatic pressure and dielectric constant are shown. It has been observed that impurity self-polarization decreases with increasing spherical dot radius and hydrostatic pressure, and binding energy increases with increasing hydrostatic pressure, which decreases with increasing spherical dot radius. The obtained results are in compatible with the previous studies.

Abstract

GaAs/Ga1-xAlxAs küresel kuantum noktasında, hidrostatik basınca bağlı dielektrik sabitinin 2p uyarılmış durum bağlanma enerjisi ve yabancı atom self-polarizasyonuna etkisi nokta yarıçapı ve basıncın fonksiyonu olarak varyasyon yöntemi kullanılarak hesaplanmıştır. Elde edilen sonuçlara göre, dielektrik sabitinin ve hidrostatik basıncın 2p uyarılmış durum bağlanma enerjisini ve yabancı atom self- polarizasyonunu değiştirdiği görülmüştür. Yabancı atom self-polarizasyon ve bağlanma enerjisi nokta yarıçapına, hidrostatik basınca ve dielektrik sabitine bağlı değişimleri gösterilmiştir. Yabancı atom self-polarizasyonun küresel nokta yarıçapı ve hidrostatik basıncın artması ile azaldığı, bağlanma enerjisinin ise küresel nokta yarıçapının artması ile azaldığı hidrostatik basıncın artması ile arttığı görülmüştür. Elde edilen sonuçlar daha önce yapılmış çalışmalar ile uyumludur.
