Анотація

Виконано чисельне моделювання формування електронно-дiркової рiдини у випадку однорiдного свiтлового опромiнення дихалькогенiдiв перехiдних металiв типу MoS2 та MoTe2. Дослiджено кiнетику захоплення екситонiв острiвцями та обчислено розподiл густини екситонiв навколо острiвцiв, враховуючи кореляцiю в положеннях острiвцiв у газi екситонiв та межовi умови при рiзнiй формi однорiдного накачування. Оцiнено розмiри острiвцiв електронно-дiркової рiдини. Встановлено оптимальне просторове розмiщення острiвцiв електронно-дiркової рiдини та залежнiсть утвореної структури вiд параметрiв системи.
