Chegaralash energiyasining GaAs dan yasalgan sferik kvant nuqtalar o’lchamiga bog’liqligi nazariy jihatdan o'rganiladi. O'tkazuvchanlik zonasidagi erkin elektronlarning energiya sathlari va kvant nuqtalarida valentlik zonasidagi teshiklar diskret ekanligi ko'rsatildi. Shuningdek, ikki sath orasidagi energiya kvant nuqtalarining o'lchamiga bog'liqligi va kvant nuqtalarining o’lchamining kamayishi bilan ortib borishi ko'rsatildi. Bundan tashqari, bizning natijalarimiz shuni ko'rsatadiki, kvant nuqtas radiusi ortishi bilan chegaralanish energiyasi kamayadi, lekin nolga etib bormaydi.
