The elastic modulii of evaporated C60 films
Surface acoustic wave (SAW) pulscs cvcrc cxcitctl in C60 films on a variety of substratcs using pulscs from Excimcr lasers for cxcitation. An optical beam deflection technique and polymer elcctrct transduccrs tvcrc utilizcd to detect the propagation of the SAW pulsc with high spatial and tcmporal resolution, allowing an accuracy of bcttcr than O.lfl/o for SAW velocity mcasuremcnts. With this te...
متن کاملNO chemisorption dynamics on thick FePc and ttbu-FePc films.
The NO chemisorption dynamics on ordered multilayer iron phthalocyanine (FePc) and quasiamorphous multilayer tetra-t-butyl FePc (ttbu-FePc) films on a Au(111) substrate was investigated using the King and Wells reflection technique. The NO zero coverage or initial sticking probabilities (S(0)) were measured as a function of sample temperature (T(s)) and beam energy (E(i)). The experimental resu...
متن کاملMorphology and interdiffusion behavior of evaporated metal films on crystalline diindenoperylene thin films
We present a transmission electron microscopy ~TEM!/Rutherford backscattering spectrometry ~RBS!/x-ray-diffraction ~XRD! study of Au evaporated on crystalline organic thin films of diindenoperylene ~DIP!. Cross-sectional TEM shows that the preparation conditions of the Au film ~evaporation rate and substrate temperature! strongly determine the interfacial morphology. In situ XRD during annealin...
متن کاملBand-Gap Tuning Of Electron Beam Evaporated Cds Thin Films
The effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated CdS thin films have been investigated. CdS thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and Atomic Force Microscopy were used to character...
متن کاملEVAPORATED SELENIUM FILMS FOR USE IN Ha PHOTOGRAPHY
0.75 Â passband and one of the chromosphere and prominences taken at the same wavelength with a 3 Â passband. This system permits study of the relationship between prominences and disk features. On April 30, 1960, while the instrument was still being adjusted, a sequence of pictures showing a fine set of loops over a large sunspot was obtained (Plate I). One end of the loops is seen clearly to ...
