2D Dirac materiallarining optik xossalari (BeN₄, IrN₄, MgN₄, PtN₄ va RhN₄): zichlik funksional nazariyasi asosidagi tadqiqot
Annotatsiya
Zichlik funksional nazariyasi (DFT) hisob-kitoblari asosida yaqinda kashf etilgan 2D Dirac materiallari — BeN₄, IrN₄, MgN₄, PtN₄ va RhN₄ — ning optik xossalari o‘rganildi. Tadqiqot natijalariga ko‘ra, ushbu materiallarning elektron va optik xossalariga metall komponentlar sezilarli darajada ta’sir ko‘rsatadi. Masalan, tajribada sintez qilingan BeN₄ materialining yutilish spektri keng spektral diapazonda Be atomlarini Rh kabi boshqa metall atomlariga almashtirish orqali ming martadan ortiq kuchaytirilishi mumkin. Bu kuchaygan yutilish holati tizimdagi holatlar zichligiga metall atomlarning katta hissa qo‘shishi bilan izohlanadi. Shuningdek, sinish ko‘rsatkichi va aks ettirish qobiliyati kabi boshqa optik parametrlar ham metall atomlarni almashtirish orqali o‘zgaradi. Ushbu natijalar past o‘lchamli bunday materiallarning optik xossalarini metall atomlarini almashtirish yo‘li bilan boshqarish imkoniyatini ko‘rsatadi.
