First and foremost, by contacting the edge of the TMDC, access to the much higher in-plane mobility is given. No van-der-Waals gaps between layers have to be overcome, instead the excitons in the layers can be extracted in parallel and the interlayer transfer time is irrelevant for the photoresponse. Second, the work function of the MoS2 on the edges is different than on the top facet, which affects the magnitude of a potential Schottky barrier at the TMDC/metal interface. Both of these effects take specific advantage of the anisotropic in-plane/out-of-plane carrier behavior in TMDCs. A third effect arises from the fact that top contacts often use adhesion layers, e.g. titanium, between the TMDC and the actual metal contact, e.g. gold. In the edge contact geometry, there is almost no contact between the TMDC and the adhesion layer, which again affects the height of a potential Schottky barrier at the interface. For the specific example of titanium vs. gold, we find that pure titanium edge contacts are faster than the top devices, but slower than Au edge devices. This is in agreement with Zhang et al. who correlated the faster response times for Au contacts with a higher Schottky barrier. All advantages of edge contacts combined lead to accelerated rise and fall times, also visible when comparing the non-steady state and Fourier transform. The representative example shown in With respect to the widely applied top contact architectures in the design of TMDC photodetectors, we note an additional complication: these contacts are typically fabricated by thermal evaporation of the metal in vacuum. Hot metal atoms induce defects and alloy formation in the top layers of the TMDC, leading to Fermi-level pinning and other potentially unwanted changes to the surface with detrimental effects on the speed of the photodetector. Several strategies have been designed to circumvent this complication, including transfer printing of metal electrodes via polymer stamps or so-called van-der-Waals electrodes. Geladari et al. have recently shown that solutions of atom precise Au32-metalloid gold clusters can be utilized as inks for direct laser-induced printing of gold contacts with diffraction-limited spatial resolution. The clusters are separated and stabilized with (nBuP12Cl8) linkers. Upon illumination at 488 nm these linkers are detached from the Au cores, which then fully agglomerate to macroscopic, metallic gold. This way, gold contacts with near bulk-like conductivities (10 6 S/m) were defined on WS2, and a fully functional photodetector was fabricated without thermal evaporation, cf. Figure . The thermal stress inflicted by such methods is only given by the absorption of light, which strongly limits the imposition on the WS2 flake. While quantitative details remain to be fully investigated, we expect such gentle contacting strategies to be advantageous in reducing the carrier injection time, which would manifest in a reduced RC time.
