Abstract Halide perovskite metasurfaces are attracting increasing interest for applications in light-emitting and display technologies. To access the wide range of colors required these applications, main mechanism exploited thus far has been chemical engineering compounds – this constitutes a significant limitation dynamic switching optical response desirable actual devices. Here we demonstrat...

scholars concern about colors application in poetic images, because color is considered one of the basic principles in images literary aesthetic field. in contemporary literature, poets portray beauty images by colors and indeed the presence of colors in nazok almalaeke poems is one of the basic rhetorical and expressive principles as other contemporary poets. in nazok almalaeke poems white is ...

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
