Atomic structure of highly strained BiFeO3 thin films.
We determine the atomic structure of the pseudotetragonal T phase and the pseudorhombohedral R phase in highly strained multiferroic BiFeO(3) thin films by using a combination of atomic-resolution scanning transmission electron microscopy and electron energy-loss spectroscopy. The coordination of the Fe atoms and their displacement relative to the O and Bi positions are assessed by direct imagi...
متن کاملHighly Conformal Thin Films of Tungsten Nitride Prepared by Atomic Layer Deposition from a Novel Precursor
Highly uniform, smooth, and conformal coatings of tungsten nitride were synthesized by atomic layer deposition (ALD) from vapors of a novel precursor, bis(tert-butylimido)-bis(dimethylamido)tungsten, (BuN)2(Me2N)2W, and ammonia at low substrate temperatures (250-350 °C). This tungsten precursor is a low-viscosity, noncorrosive liquid with sufficient volatility at room temperature to be a vapor ...
متن کامل- Atomic Spectra Atomic Structure
T HE present edition of this work contains a number of corrections and additions; Birge's new set of fundamental constants has been adopted throughout, and various tables, especially the table of ionization potentials, have been brought up to date. The author is indebted to Professor J. W. Ellis of the University of California at Los Angeles for a list of errors and corrections ; several of the...
متن کاملAtomic Simulation of Temperature Effect on the Mechanical Properties of Thin Films
The molecular dynamic technique was used to simulate the nano-indentation test on the thin films of silver, titanium, aluminum and copper which were coated on the silicone substrate. The mechanical properties of the selected thin films were studied in terms of the temperature. The temperature was changed from 193 K to 793 K with an increment of 100 K. To investigate the effect of temperature on...
متن کاملAdsorption of Au and Pd Atoms on Thin SiO2 Films: the Role of Atomic Structure
The low-temperature deposition of Au and Pd atoms on thin SiO2 films grown on Mo(112) has been studied by scanning tunneling microscopy (STM), infrared reflection absorption spectroscopy, and CO adsorption. On the monolayer films, gold forms three-dimensional nanoparticles at temperatures as low as 10 K and does not affect the phonon spectra of the silica films. On the other hand, palladium exh...
