The results and conclusions in this section are based on our work with two-terminal lateral photodetectors based on MoS2 or WSe2, which we use as a model device architecture due to its cost-effective fabrication. A key result of these studies is that such simple photodetectors are essentially all limited by the RC constant of the device. While this may not necessarily be true for more complicated TMDC photodetectors, such as gated three-terminal devices, vertical geometries or heterostructures, we believe that the considerations here should be widely applicable also to other TMDC materials within two-terminal lateral detectors. Therefore, this section focuses on strategies for decreasing the RC time, which are validated by monitoring the overall effect on the extrinsic photoresponse.
