Tóm tắt
Trong bài báo này, chúng tôi nghiên cứu sự tồn tại của hiệu ứng Stark quang học của exciton trong chấm lượng tử phỏng cầu dạng dẹt bằng lý thuyết hàm sóng tái chuẩn hóa. Một sóng bơm mạnh đã được áp dụng để kết cặp các trạng thái lượng tử hóa của điện tử trong vùng dẫn trong mô hình hệ ba mức. Chúng tôi quan sát thấy hai vạch phổ hấp thụ liên vùng riêng biệt, thể hiện sự tách các mức năng lượng của điện tử do hiệu ứng Stark quang học. Đồng thời, các ảnh hưởng của năng lượng trường bơm, kích thước và dạng hình học của chấm lượng tử lên các đặc trưng của hiệu ứng cũng được khảo sát chi tiết.
