چکیده

در این پژوهش، نانوکامپوزیت RGO-BrInPcبا احیای شیمیایی اکسید گرافن با استفاده از هیدرات هیدرازین در حضور بروموایندیوم فتالوسیانین (BrInPc) و سدیم دودسیل سولفات (SDS) سنتز شد. نتایج طیف‌سنجی FTIR و UV-Vis نشان داد که مولکول‌های BrInPc بر روی صفحات RGO توسط برهمکنش π-π متصل می‌شوند. خواص الکتریکی نانوکامپوزیت های RGO-BrInPc در محدوده دمایی 393- 298کلوین مورد بررسی قرار گرفت. سپس چندین دستگاه مسطح بین دیجیتالی با ضخامت 30 نانومتر و فاصله بین الکترودها 200 میکرومتر از نانوکامپوزیت RGO-BrInPc ساخته شد. تغییرات جریان برحسب دما در 3 ولت ثابت نشان داد که شکاف باند نانوکامپوزیت RGO-BrInPcبه عنوان تابعی از نرخ احیاء GO در نانوکامپوزیت تغییر می کند.

چکیده English

In this research, RGO-BrInPc nanocomposite was synthesized by chemical reduction of graphene oxide using hydrazine hydrate in the presence of bromoindium phthalocyanine (BrInPc) and sodium dodecyl sulfate (SDS). The results of FTIR and UV-Vis spectroscopy showed that the BrInPc molecules on the RGO sheets are connected by π-π interaction. The electrical properties of RGO-BrInPc nanocomposites were investigated in the temperature range of 298-393 K. Then, several planar interdigital devices with a thickness of 30 nm and a distance between electrodes of 200 μm were fabricated from RGO-BrInPc nanocomposite. The varation of current in terms of temperature at constant 3 V showed that the band gap of RGO-BrInPc nanocomposite changes as a function of the reduction rate of GO in the nanocomposite.
