WebMar 15, 2024 · Here we report a straightforward approach to realize single-crystalline perovskite arrays through a relatively simple pattern-selective molecular epitaxial growth. This approach is applied to create diverse shaped perovskite arrays, such as hexagon, triangle, circle, square, and rectangle. WebApr 7, 2024 · The size of crystalline nanoparticles is estimated by the Scherrer formula, (2) Where, D is the volume weighted crystallite size (nm), k is the shape factor (k = 0.94), λ is the X-ray wavelength (1.54056 Å), θ is the diffraction angle of Bragg and β is the expanded diffraction peak measured at FWHM (in radians).
