Intersubband Transitions in Nonpolar ZnO/BeMgZnO Quantum Wells: Effects of Physical Dimension, Concentration and Donor Level

Öz:
Polarizaton properties of ZnO well layers on BeMgZnO barrier layers grown in polar and semipolar orientations have been investigated. Cases of relaxed and strained barrier layers are considered. It is found that the polarizaton difference at the interfaces leads to a built-in electric field inside the well layer as much as 8 MV cm^(-1) in magnitude. Nonpolar ZnO/BeMgZnO quantum wells have been studied in terms of intersubband transitions. The calculations have covered Be and Mg concentrations up 0.18 and 0.5, respectively. It has been found that intersubband transition (ISBT) energies ranging from 50 to 700 meV are possible. The effect of barrier thickness on the ISBT energies has been studied. The results indicate insignificant changes in ISBT energies compared to the energies.

Polar Olmayan ZnO/BeMgZnO Kuantum Kuyularında Altbantlar Arası Geçişler: Fiziksel Boyut, Konsantrasyon ve Donör Seviyesinin Etkileri

Öz:
Polar ve semipolar yönlerde büyütülen BeMgZnO bariyer tabakaları üzerindeki ZnO kuyu katmanlarının polarizasyon özellikleri araştırıldı. Gevşemiş ve gerilmiş bariyer katmanların durumları göz önünde bulunduruldu. Arayüzlerdeki polarizasyon farkının, kuyu tabakası içinde 8 MV cm^(-1) büyüklüğünde yerleşik bir elektrik alanına yol açtığı bulundu. Polar olmayan ZnO/BeMgZnO kuantum kuyuları, altbantlar arası geçişler açısından incelendi. Hesaplamalar Be ve Mg konsantrasyonlarını sırasıyla 0.18 ve 0.5'e kadar kapsamaktadır. 50 ila 700 meV arasında değişen altbantlar arası geçiş (ISBT) enerjilerinin mümkün olduğu bulundu. Bariyer kalınlığının ISBT enerjileri üzerindeki etkisi incelendi. Sonuçlar, enerjilere kıyasla ISBT enerjilerinde önemsiz değişiklikler olduğunu göstermektedir.
