In this report, the relationship between the dimer index (N) and the prohibition level of Stanene material is studied and investigated by applying the density functional theory (DFT) method. The results of investigating the change in the N index from 6, 7, 8, 9 and 10 show that the ability to prohibit the zone from changing according to regulations is consistent with previous studies on materials such as silicene and graphene, germanene, specifically prohibits the extended band with a magnitude of 0.36 eV
0.42 eV
0.24 eV
0.25 eV and 0.28 eV. Thereby, stanene material is determined to be a semiconductor material, without magnetic properties. However, if stanene adsorbs halogen elements, the new material obtained is a magnetic material. This potential material is suitable for manufacturing new generation devices such as halogen element search sensors, spin motors, and field-effect transistors in the future.Trong báo cáo này, mối liên hệ giữa chỉ số dimer (N) và năng lượng vùng cấm của vật liệu Stanene được nghiên cứu, khảo sát bằng cách áp dụng phương pháp lý thuyết phiếm hàm mật độ (DFT).
