Abstract. We analyse a model describing hysteretic behaviour of the reflectivity R for the system ‘graphene–Pb(ZrxTi1–x)O3 (PZT) ferroelectric substrate–gate’ with a gate voltage variation, which takes into account trapping of electrons into the graphene–PZT interface states. We demonstrate that the hysteresis in the R parameter can be observed experimentally for the telecommunication-range radiation (the wavelength λ = 1.55 μm) at low gate voltages and, moreover, the phenomenon can be used while creating fast bistable systems for the novel non-volatile memory devices with on-chip optical interconnection

Анотація. Проаналізовано модель гістерезисної поведінки коефіцієнта відбивання системи „графен–сегнетоелектрична підкладка Pb(ZrxTi1–x)O3 (PZT)–затвор” зі змінною напругою на затворі з урахуванням захоплення електронів на інтерфейсні стани на межі графен–сегнетоелектрик. Показано, що такий гістерезис можна спостерігати експериментально для випромінювання телекомунікаційного діапазону (λ = 1,55 мкм) для низьких напруг на затворі та можна використати у створенні швидкодійної бістабільної системи для нових пристроїв енергонезалежної пам’яті з оптичними з’єднаннями на чіпах.
