Piezoelectric biomaterials have attracted significant attention due to the potential effect of piezoelectricity on biological tissues and their versatile applications. However, the high cost and complexity of assembling and domain aligning biomolecules at a large scale, and the disordered arrangement of piezoelectric domains as well as the lack of ferroelectricity in natural biological tissues remain...
Organometal halide perovskite material was investigated as a promising candidate for resistive random-access memory (RRAM). In order to improve the stability of perovskite RRAM, a polymethyl methacrylate (PMMA) interlayer was inserted between perovskite and metal electrode. High ON-OFF current ratio (106) and operating voltage as low as 0.5 V were achieved in the PMMA encapsulated perovskite RRAM.
High performance CH3NH3PbI3 perovskite photodetectors are realized by applying thin films of fullerene derivatives as interfacial layers between the metal contact and the perovskite materials. The perovskite photodetector with PC61BM interlayer demonstrates much better performance than that with IC60BA interlayer, reaching a responsivity of 57.6 mA/W. The influences of different fullerene derivatives...
