摘要：Graphene-based hybrid photo detectors are promising for weak-light detection with high photo gain. In this paper, we focused on the details of the scaling effect on grapheme-based hybrid photo detectors. By designing a series of devices with different sizes from 10*10μm2 to 100*100μm2, we found that the photocurrent generally decreases with increased channel length but decreased channel width. Our study would be useful for clarifying the real potential of photo gating effect in image applications.
