“…Similar to the case of perovskite solar cells, [84] the development of optoelectronic devices based on 2DP/TMD stacks significantly outpaced the understanding of their fundamental properties. Despite successful demonstrations of photodetectors or photovoltaic devises based on van der Waals heterostructures composed of 2DPs and TMDs or other layered materials, [23,24,27,[85][86][87][88][89] still very little is know about the fundamental mechanisms standing behind their operation. Most published work focuses on the device performance and only a few publications attempt to provide a more detailed understanding of the photophysics, excitation transfer mechanism and mutual impact of the layers.…”

Two-dimensional (2D) layered materials have been in the spotlight of scientists' interest for more than a decade. The inherently weak interaction between the layers in 2D crystals allows stacking different materials and building heterostructures with novel functional properties. Here, we review the most recent advances on heterostructures composed of transition metal dichalcogenides and 2D perovskites. We show that combining these materials yields a rich and unique platform for the investigation of energy and charge transfer mechanisms, as well as band alignment engineering. We summarize the current understanding of the fascinating photophysics of these heterostructures, emphasizing the open questions related to their fundamental properties. We conclude by highlighting how this platform offers an unprecedented number of tuning knobs to control their optoelectronic properties and some potentially interesting directions to explore in the near future.

“…Singlelayer WS 2 is a direct semiconductor, which explains the PL enhancement 93 . Besides the free charge transfer, ex-citonic energy transfer from the exciton state of (C 6 H 5 C 2 H 4 NH 3 )PbI 4 to an upper-lying exciton state of WS 2 is also possible 95,155 . Interestingly, even the deeper perovskite layers contribute to the energy transfer, leading to a large enhancement of PL from WS 2 95 .…”

Transition metal dichalcogenides (TMDs) and perovskites are among the most attractive and widely investigated semiconductors in the recent decade. They are promising materials for various applications, such as photodetection, solar energy harvesting, light emission, and many others. Combining these materials to form heterostructures can enrich the already fascinating properties and bring up new phenomena and opportunities. Work in this field is growing rapidly in both fundamental studies and device applications. Here, we review the recent findings in the perovskite-TMD heterostructures and give our perspectives on the future development of this promising field. The fundamental properties of the perovskites, TMDs, and their heterostructures are discussed first, followed by a summary of the synthesis methods of the perovskites and TMDs and the approaches to obtain high-quality interfaces. Particular attention is paid to the TMD-perovskite heterostructures that have been applied in solar cells and photodetectors with notable performance improvement. Finally through our analysis, we propose an outline on further fundamental studies and the promising applications of perovskite-TMD heterostructures.

Organic-inorganic hybrid perovskites have attracted considerable attention for developing novel optoelectronic devices owing to their excellent photo responses. However, conventional nanolithography of hybrid perovskites remains a challenge because they undergo severe damage in standard lithographic solvents, which prohibits device miniaturization and integration. In this study, a novel transparent stencil nanolithography (tSL) technique is developed based on focused ion beam (FIB)assisted polyethylene terephtha late (PET) direct patterning. The proposed tSL enables ultrahigh lithography resolution down to 100 nm and accurate stencil mask alignment. Moreover, the stencil mask can be reused more than ten times, which is costeffective for device fabrication. By applying this lithographic technique to hybrid perovskites, a highperformance 2D hybrid perovskite heterostructure photodetector is fabricated. The responsivity and detectivity of the proposed heterostructure photodetector can reach up to 28.3 A W −1 and 1.5 × 10 13 Jones, respectively. This tSL nanolithography technique based on FIBassisted PET direct patterning can effectively support the miniaturization and integration of hybridperovskitebased electronic devices.
