Abstract
In this study, a facile melt-mixing technique was employed as a simple and inexpensive technique to prepare a quasi-2D graphene-PVDF (QGF-PVDF) nanocomposite based FET (QGF-FET) device. The morphological and optical properties were studied using field emission scanning microscopy (FE-SEM) and UV–visible diffuse-reflectance spectrum (UV–Vis DRS). Morphological study reveals that the thin films of QGF-PVDF are highly affected by the calcination temperature, as reflected also in their optical properties. The optical band gap reveals a Bathochromic shift due to increased calcination time from 12 to 24 hr. Our results further suggest that the QGF-FET device can potentially exhibit superior photodetector performance for photocurrent up to 20 mA.
