Thin films of vapor-deposited Ni(II) and Co(II) complexes of tetraphenylporphyrin (NiTPP and CoTPP) were studied supported on gold and embedded in Al-Al(2)O(3)-MTPP-Pb tunnel diodes, where M = Ni or Co. Thin films deposited onto polycrystalline gold were analyzed by ultraviolet photoelectron spectroscopy (UPS) using He I radiation. Scanning tunneling microscopy (STM) and orbital-mediated tunnel...

Thin film electrode production and characterization for heat cell studies are described. The objective is two-fold: maximizing excess heat production and insuring a long lifetime and electrolysis. To do this in a reproducible faction, a pre-and post-run analysis of the films was carried out using various probe techniques. In this study, various Pd-Ni thin films were manufactured using with a ma...

We show that nanosecond pulsed laser interference can be used to structure surfaces on a nanoscale. With this method, we are able to create hollow structures on various thin films like Ta, Ni, Au, Cu, Co, and NiTi. We find that the structuring mechanism is related to the mechanical effect of thermal expansion upon melting. To corroborate this model, we study materials with an abnormal behavior ...

Metal particles (Au, Pd and Ni) with an average diameter between 7 to 100 ,~ have been prepared on thin metal oxide films (TiO 2, MgO and A1203), epitaxially grown on refractory metal substrates {Mo(100) or Re(0001)}, and imaged using scanning tunneling microscopy (STM). Information regarding the local electronic structure has been obtained using scanning tunneling spectroscopy (STS). Controlle...

%e have measured the surface-acoustic-wave velocities in Ni/V superlattices using both Brillouin scattering and surface-acoustic-wave techniques; the results are in good quantitative agreement. These results confirm earlier reports of phonon-velocity softening in bcc/fcc superlattices and prove that this is a general phenomenon, not a consequence of the measurement method. In addition, we descr...

Irradiation experiments were conducted on multilayer (ML) and coevaporated (CO) thin films in order to examine the role that the heat-of-mixing (AH,,,,,) has in ion-induced gram growth. Room-temperature irradiations using 1.7 MeV Xe were performed in the High Voltage Electron Microscope at Argonne National Laboratory. The alloys studied (Pt-Ti, Pt-V, Pt-Ni, Au-Co and Ni-Al) spanned a large rang...
