Abstract The high occurrence of trapped unreactive charges due to chemical defects seriously affects the performance g‐C 3 N 4 in photocatalytic applications. This problem can be overcome by introducing ultrasmall red phosphorus (red P) crystals on sheets. elemental P atoms reduce number structure forming new bonds for much more effective charge separation. product shows significantly enhanced activity toward hydrogen production. To best our knowledge, evolution rate obtained this hybrid...
Abstract Two-dimensional semiconductors can be used to build next-generation electronic devices with ultrascaled channel lengths. However, need integrated high-quality dielectrics—which are challenging deposit. Here we show that single-crystal strontium titanate—a high- κ perovskite oxide—can two-dimensional using van der Waals forces. Strontium titanate thin films grown on a sacrificial layer, lifted off and then transferred onto molybdenum disulfide tungsten diselenide make n-type p-type...

Graphitic carbon nitride (g-C3N4) fundamental photophysical processes exhibit a high frequency of charge trapping due to physicochemical defects. In this study, copper phosphide (Cu3P) and g-C3N4 hybrid was synthesized via facile phosphorization method. Cu3P, as an electron acceptor, efficiently captures the photogenerated electrons drastically improved separation rate cause significantly enhanced photocatalytic performance. Moreover, robust intimate chemical interactions between Cu3P offers...

Room-temperature polar skyrmions, which have been recently discovered in oxide superlattice, received considerable attention for their potential applications nanoelectronics owing to nanometer size, emergent chirality, and negative capacitance. For practical applications, manipulation using external stimuli is a prerequisite. Herein, we study the dynamics of individual skyrmions at nanoscale via situ scanning transmission electron microscopy. By monitoring electric-field-driven creation,...
In recent years, organic–inorganic hybrid perovskite solar cells (PSCs) have attracted extensive attention due to their high power conversion efficiency (PCE) and simple preparation process. The selection optimization of the hole transport layer (HTL) are very important for device performance. Compared other HTLs, nickel oxide (NiOx) has been widely used in PSCs its good chemical stability, mobility, method. This review begins with application NiOx HTL planar systematically introduces...
