Enhancing the photo-response characteristics of graphene/n-Si based Schottky barrier photodiodes by increasing the number of graphene layers

Fidan, Mehmet; Ünverdi, Özhan; Çelebi, Cem (American Vacuum Society, 2022)

The impact of the number of graphene layers on the spectral responsivity and response speed of graphene/n-type Si (Gr/n-Si)-based Schottky barrier photodiodes is investigated. Gr/n-Si photodiode devices are fabricated by ...
Graphene/SOI-based self-powered Schottky barrier photodiode array

Yanılmaz, Alper; Fidan, Mehmet; Ünverdi, Özhan; Çelebi, Cem (American Institute of Physics (AIP), 2022)

We have fabricated a four-element graphene/silicon on insulator (SOI) based Schottky barrier photodiode array (PDA) and investigated its optoelectronic device performance. In our device design, monolayer graphene is utilized ...
Light-induced modification of the Schottky barrier height in graphene/Si based near-infrared photodiodes

Fidan, Mehmet; Dönmez, G.; Yanilmaz, A.; Ünverdi, Özhan; Çelebi, Cem (Elsevier B.V., 2022)

The impact of light on the Schottky barrier height (SBH) in p-type graphene/n-type Si (p-Gr/n-Si) based near-infrared photodiodes is investigated. Hall effect and optoelectronic transport measurements carried out under ...
