[Raman Applicaiton] Inspect the existence of graphene in IGZO thin film by Raman spectra

Raman spectra can be used to inspect the existence of graphene in IGZO thin film.

Graphene, which was synthesized using chemical vapor deposition (CVD), was transferred onto the polyimide substrate.

Graphene can enhance physical properties of IGZO thin film.

PTT's micro Raman spectrometer is used to inspect the existence of graphene in IGZO thin film.
