Epitaxial growth and surface morphology of aluminum films deposited on mica studied by transmission electron microscopy and atomic force microscopy

Adsorption State and Morphology of Anthraquinone-2-carboxylic Acid Deposited from Solution onto the Atomically-Smooth Native Oxide Surface of Al(111) Films Studied by Infrared Reflection Absorption Spectroscopy, X-ray Photoelectron Spectroscopy, and Atomic Force Microscopy

“…The root-mean-square roughness (Rms) of a 1 × 1 μm area of atomically-smooth Al films was 0.47 ± 0.17 nm. 35 The oxygen-dc glow discharge had no effect on the surface smoothness of the Al films.…”

“…[28][29][30][31][32][33][34][35] The deposition was conducted in a metal bell-jar evaporator equipped with a liquid-nitrogentrapped 6 in. diffusion-pump.…”

“…The peak in the histogram represents the distribution of zij and its width (full width at half maximum, W) is a good measure of the surface roughness. [30][31][32][33][34][35][36] If zij distributes randomly around the surface height at 0 nm, the resulting peak has a Gaussian shape with the standard deviation Rms. Thus, W is represented by 2.36Rms and most (>95%) areas of the peak are in the 2W region between ±W.…”

“…31,[33][34][35] The average values and standard deviations of W, Rms, and W/Rms of the images are given in Table 1, where the numbers in parentheses are those of the images used for the calculations. 35 The surface of the oxidized Al film prepared at room temperature is rough (Rms = 1.80 ± 0.94 nm and W = 1.93 ± 0.39 nm). The surface of the Al film consists of spherical grains with diameters of about 100 nm.…”

“…The transmission electron diffraction (TED) patterns of the atomically-smooth Al films show that the film consists of crystals with (111) planes. 28,29,35 We have used AFM and X-ray photoelectron spectroscopy (XPS) to characterize the morphology and adsorption state of tetracyanoquinodimethane (TCNQ) deposited from various solutions onto the atomicallysmooth oxide surfaces of Al(111) films. [30][31][32][33] The atomicallysmooth native oxide surfaces of Al(111) films are useful for conducting detailed morphology observations of deposited species on alumina.…”
