“…The I–V relationship of Ln ( V ) versus Ln ( I ) at LRS revealed a linear dependence on voltage with a slope of approximately of1 in Figure a,c, indicating an ohmic‐like contact. Also, it corresponded to a typical conductive filament formed in the Cs 4 PbBr 6 layer . Compared with other metal electrodes, the Au top electrode can form an ohmic contact as discussed in the previous report, which was further verified in our work.…”

All‐inorganic halide perovskite Cs4PbBr6 thin films are synthesized at low temperature through a facile chemical deposition method. The deposited films are implemented as a dielectric and dissolvable layer with the Au/Cs4PbBr6/PEDOT:PSS/ITO configuration for transient memory electronic devices. The bipolar resistive switching phenomena, good switching cycling (endurance), and long data retention (104 s) are demonstrated on as‐grown nonvolatile memory device to evaluate its high stability, reliability, and reproducibility. The I–V relationship shows ohmic conduction behavior at the low‐resistance state, whereas space charge limited current mechanism is dominating at the high‐resistance state. The conductive filaments formation and rupture, accompanied by Br− vacancies in Cs4PbBr6 layer, are employed to elucidate switching mechanism. More interestingly, the soluble insulation layer of the devices is quickly dissolved and the color of films transforms from yellow to white as fast as 2 s in deionized water, which exhibits good transient performance. Moreover, the electrical characteristics as well as optical properties vanish absolutely to further demonstrate the abovementioned transition after the memory devices dissolve in deionized water. This work offers a novel way to prepare disposable electronic memory devices by utilizing cheap perovskite‐based materials for transient electronics memory area as well as implantable electronics systems.

The recent success of organometallic halide perovskites (OHPs) in photovoltaic devices has triggered lots of corresponding research and many perovskite analogues have been developed to look for devices with comparable performance but better stability. Upon the preparation of all inorganic halide perovskite nanocrystals (IHP NCs), research activities have soared due to their better stability, ultrahigh photoluminescence quantum yield (PL QY), and composition dependent luminescence covering the whole visible region with narrow line-width. They are expected to be promising materials for next generation lighting and display, and many other applications. Within two years, a lot of interesting results have been observed. Here, the synthesis of IHPs is reviewed, and their progresses in optoelectronic devices and optical applications, such as light-emitting diodes (LEDs), photodetectors (PDs), solar cells (SCs), and lasing, is presented. Information and recent understanding of their crystal structures and morphology modulations are addressed. Finally, a brief outlook is given, highlighting the presently main problems and their possible solutions and future development directions.

“…In addition, it can also be improved by improving the quality of the QDs film and the state of the interface. [65] In addition to the above devices, CHP QDs can also be used in other optoelectronic devices, such as memoristors, [66] magnetic devices [67] and electrostrictive device. [68] However, there are still some problems that need to be solved, among which the problem of poor stability is particularly prominent.…”

Colloidal halide perovskite (CHP) quantum dots (QDs)/nanocrystals (NCs) have superior optoelectronic properties, such as high optical absorption coefficient, high photoluminescence quantum yield (PLQY), tunable bandgap, composition‐related luminescence, and low manufacturing cost, which have been considered as promising low‐dimensional semiconductor materials. Profiting from these unique characteristics, CHP NCs could be widely used in various optoelectronic devices, including light‐emitting diodes (LEDs), photodetectors (PDs), solar cells (SCs), and lasers. Synthesis is the basis for the wide use of CHP NCs, which plays a vital role in the research, development and application of CHPs. Therefore, we summarize the recent synthetic strategies, and their influencing factors (e. g., the effects of ligands, and anion exchange). Besides, a summary of their optoelectronic applications is plainly mentioned. Finally, we make a brief prospect and summarize the current problems and possible solutions of this area.
