摘要：
We report on the photovoltaic effect in a WSe2/MoSe2 heterojunction, demonstrating gate tunable current rectification with on/off ratios of over 10(4). Spatially resolved photocurrent maps show the photovoltaic effect to originate from the entire overlap region. Compared to WSe2/MoS2 heterostructures, our devices perform better at long wavelengths and yield higher quantum efficiencies, in agreement with Shockley-Queisser theory. (C) 2015 AIP Publishing LLC.
