“…The on/off ratio of the graphene-only device is ≈3.5, which is comparable to previous reports. [34,37,44] The positive Dirac voltage (V Dirac ) of 60 V indicates a p-type character of the pristine graphene, [37,45] which is in agreement with the Raman shift. The photoresponse of the pristine graphene is negligible in the white light illumination condition, as shown in Figure S6 in the Supporting Information.…”

Van der Waals (vdW) heterostructures open up excellent prospects in electronic and optoelectronic applications. In this work, mixed‐dimensional metal‐halide perovskite/graphene heterostructures are prepared through selective growth of CH3NH3PbBr3 platelets on patterned single‐layer graphene using chemical vapor deposition. Preferred growth of single‐crystal CH3NH3PbBr3 platelets on graphene surfaces is achieved, which is accompanied by significant photoluminescence quenching. Raman spectra reveal that perovskite platelets cause p‐type doping in the graphene layer. A significant Fermi level decrease of 272 meV in graphene is estimated, which corresponds to a high doping density of 7.5 × 1012 cm−2. Surface potentials measured by Kelvin probe force microscopy indicate a negatively charged perovskite surface under illumination, which is consistent with the upward band bending deduced from conducting atomic force microscopy measurements. Moreover, a field‐effect phototransistor is fabricated using the perovskite/graphene heterostructure channel, and the increased Dirac voltage under illumination confirms an enhanced p‐type character in graphene. These findings enrich the understanding of strong interface coupling in such mixed‐dimensional vdW heterostructures and pave the way toward novel perovskite‐based optoelectronic devices.

“…[151][152][153][154][155][156] Xia et al [157] demonstrated a single-layer and few-layer graphene-based transistor photodetector with ultrafast photoresponse characteristics, wide optical absorption wavelength, and good internal quantum efficiency. Although graphene photodetectors exhibit excellent photodetector behavior, [158][159][160][161] it is difficult to open zero bandgaps, and low light absorption [162][163][164] (only 2.3% light absorptivity) limits its application in photodetection devices. Subsequently, many 2D semiconductor materials were successively prepared and widely used in the field of photodetectors and exhibited good optical responsiveness and a fast response rate.…”

Self‐powered photodetectors are considered as a new type of photodetectors enabling self‐powered photodetection without external power. The excellent photoresponsivity, fast photoresponse rate, low dark current, and large light on/off ratio of these photodetectors have attracted wide interest among scholars. 2D materials are widely used in self‐powered photodetectors due to their excellent optical and electrical properties, unique 2D structures, and their capabilities to exhibit excellent photodetection performance. According to the self‐driving mechanism of 2D material‐based self‐powered photodetectors, they are divided into three categories: p–n junction photodetectors, Schottky junction photodetectors, and photoelectrochemical photodetectors. From these three perspectives, the research progress of 2D material‐based self‐powered photodetectors is summarized in detail here. Research reports indicate that 2D material‐based self‐powered photodetectors have excellent self‐powered photoresponse behavior, good light on/off characteristics, and wideband spectral response ranges. The excellent photoresponse performance of 2D material‐based self‐powered photodetectors facilitates their potential applications in the field of optoelectronic devices. In particular, self‐powered photodetectors have great potential as novel emerging self‐driven optoelectronic devices. Finally, directions for the further development of 2D material‐based self‐powered photodetectors are anticipated.

Corneal neovascularization (CNV) is a common pathological change in ocular surface diseases. It is not only the factor that affects vision but also the main cause for corneal graft failure. Based on the mechanism of CNV, many achievements have been developed to suppress the formation of CNV. There are certain novel drugs such as aflibercept, gold nanoparticles, and netrins which provide us with new clues to treat CNV. However, we still need to develop more effective therapeutic drugs. It is of great significance to develop new effective drugs to suppress the occurrence of CNV. In this paper, recent drug therapies for CNV are reviewed. The electronic database (PubMed) is searched for relative basic research and randomized clinical trials that are published recently.
