Дослiджено просторову та часову дисперсiї дiелектричної проникностi електронного газу в квазiдвовимiрних квантових наноструктурах. Вперше розглядається задача про екранування потенцiалу, що розсiює, носiїв заряду в квантово-розмiрнiй плiвцi з модифiкованим потенцiалом Пешля–Теллера. Отриманi аналiтичнi вирази для дiелектричної проникностi.
