Electronic and optical properties of a screened donor impurity in a two-dimensional quantum dot under THz laser field

Abstract

Merkezde perdelenmiş Coulomb safsızlığına sahip iki boyutlu bir parabolik kuantum noktasının yoğun THz lazer alanına bağlı optik cevabının araştırılması, yüksek frekanslı Floquet teorisi çerçevesinde gerçekleştirilmiştir. Sistemin enerji spektrumu ve dalga fonksiyonları sonlu elemanlar yöntemi kullanılarak elde edilirken, optik soğurma katsayıları ve kırılma indisi değişiklikleri kompakt yoğunluk matrisi yaklaşımına göre hesaplanmaktadır. Sonuçlarımız, yoğun lazer alanının sistem üzerindeki etkisinin elektronik ve optik özelliklerde önemli değişikliklere yol açtığını vurgulamaktadır. Ayrıca, optik katsayıların pik genliği ve konumunun, perdeleme parametresi ve hapsetme şiddetinin değiştirilerek ayarlanabileceğini bulduk. Bu özelliklerin kontrol edilebilirliği optoelektronik cihazların optimizasyonunda faydalı olabilir.
