- Аннотация: Graphene oxide (GO), with its tunable electronic properties and bandgap, has emerged as a promising material for next-generation semiconductor applications. However, the presence of oxygen-containing functional groups in GO disrupts its conjugated π-network, reducing conductivity and thermal stability, thus limiting its practical applications. In this work, hydrazine and hydroquinone are employed as reducing agents to optimize the reduction process of GO and improve its electrical and structural properties. The structural transformations of GO and reduced GO (RGO) are analyzed using FTIR, Raman spectroscopy and UV-vis spectroscopy. The results reveal that both reducing agents effectively reduced oxygen functional groups and restored sp² hybridized carbon structures, with hydrazine showing a stronger reducing capability but causing more structural defects, whereas hydroquinone results in a more controlled reduction process. The outcomes highlight the potential of these reduction strategies for enhancing GO’s performance in advanced electronic applications, including memory devices and field-effect transistors.
