Теорiю функцiонала щiльностi застосовано до розгляду електронних властивостей чистого i легованого азотом вурциту ZnO. Метод Хаббарда U (DFT + Ud + Up) використано для корекцiї недооцiнки величини забороненої зони. Результати ї ї розрахунку виявилися вiдповiдними наявним експериментальним даним. Розглянуто чотири рiзнi конфiгурацiї легованого азотом вурциту ZnO. Показано, що величина забороненої зони для ZnO залежить вiд концентрацiї азоту.
