Abstract The intrinsic photocurrent generation mechanism of a self-assembled graphene p–n junction operating at 1.55 μ is investigated experimentally. It is concluded that both a photovoltage effect and a photothermoelectric effect contribute to the final photocurrent. The photocurrent signal at the p–n junction was found to be dominated by photothermoelectric current, arising from different self-assembled doping levels.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
