Layered materials offer several ways of contacting: bottom electrodes beneath the TMDC, top electrodes above the material, and a sandwich structure in a vertical stack or so-called "edge contacts" at the edges of the material. A key result of our work with MoS2 is that edge contacts provide unique advantages for the speed of photodetectors based on anisotropic 2D materials, such as TMDCs. With the unravelling of the edge, for example by plasma etching, there is direct access to the layers which differ chemically tremendously from the surface. They have been shown to provide a lower contact resistance, a smaller transfer length or a higher capability of charge carrier injection. We find that this contact style accelerates the fall time of the photodetectors by more than an order of magnitude (Figure ). This result is presumably the combination of three effects:
