Rosen-Morse Kuantum Kuyusunun Safsızlıkla İlgili Doğrusal Olmayan Optik Özellikleri

Bu çalışmada, dış statik elektrik ve manyetik alanın Rosen-Morse kuantum kuyusundaki temel durumla ilişkili hidrojenik donor safsızlık atomunun bağlanma enerjisi üzerindeki etkisi teorik olarak etkin kütle yaklaşımında varyasyonel bir yöntem kullanılarak araştırılmıştır. Bu yapıdaki safsızlıkla ilişkili doğrusal olmayan optik özellikler, kompakt yoğunluklu matris yaklaşımı kullanılarak hesaplanmıştır. Doğrusal olmayan optik özelliklerin sayısal sonuçları, merkezi donor safsızlığı için statik elektrik ve manyetik alanın iki farklı değeri için gelen foton enerjisinin fonksiyonları olarak sunulmuştur. Ayrıca, hidrojenik donorsafsızlığının bağlanma enerjisi, statik elektrik ve manyetik alanın bir fonksiyonu olarak gösterilmiştir. Sonuç olarak, yapının doğrusal olmayan optik özelliklerinin, donor atomunun varlığından ve statik elektrik ve manyetik alanların büyüklüğünden önemli ölçüde etkilendiği bulunmuştur.

Impurity-Related Nonlinear Optical Properties of Rosen-Morse Quantum Well

In this present study, the effect of external static electric and magnetic field on the binding energy of hydrogenic donor impurity associated with the ground state in Rosen-Morse quantum well were theoretically investigated by using a variational method in the effective-mass approximation. The impurity-related nonlinear optical properties in this structure were calculated by using the compact-density-matrix approach. The numerical results of nonlinear optical properties were presented as functions of incident photon energy for two different values of the static electric and magnetic field for on-center donor impurity. Moreover, the binding energy of the hydrogenic donor impurity was shown as a function of static electric and magnetic field. As a result, it was found that the nonlinear optical properties of the structure were significantly affected by the impurity atom and the magnitude of static electric and magnetic fields.
