Ultra high vacuum scanning tunneling microscopy to study thin film growth
(1994)
An ultra high vacuum chamber was constructed to study thin film growth using scanning tunneling microscopy (STM). The sample stage is specially designed so that samples can be transferred in situ among various film preparation ...
Photoelectron spectroscopy of negative cobalt clusters: Correlation of promotion energy to reactivity
(1992)
Photoelectron spectra of negatively charged cobalt clusters in the size range of 4-26 atoms have been obtained. The electron affinity (E.A.) values along with the reported ionization potential (I.P.) have been used to ...
Heat conduction for dielectric thin films from the Casimir to diffusion limit
(1994)
The heat transfer in electrically insulating thin film materials is predominantly governed by phonons and is accurately described when the phonon mean free path is either much smaller than the order of the thickness of the ...
The designer optical resonances of metal nanoshells
(1998)
Metal nanoshells consist of a dielectric or semiconducting core coated with a metallic layer of nanometer scale dimensions. Gold nanoshells with silica cores were fabricated by first attaching gold colloid to the surface ...
Magnetic and chemical effects in x-ray resonant exchange scattering in rare earths and transition metal compounds
(1994)
The increased availability of synchrotron x-ray sources has facilitated the development of new diffraction techniques based on x-ray resonant exchange scattering (XRES). Resonant electric dipole (E1) and quadrupole (E2) ...
A theoretical study of cluster reactivity and the effects of electric field on adatom-surface bond
(1996)
We have used the density functional ab initio method to study the reactivity of small clusters (ammonia reacting with GaAs clusters), and the effects of electric field on adatom-surface interactions (H and Al adsorbed on ...
Functionalization of scanning tunneling microscope probes with buckminsterfullerenes
(1996)
This dissertation analyzes the feasibility and advantages of molecular functionalization of scanning tunneling microscope (STM) probes with buckminsterfullerenes. The C$\sb{60}$ molecules are adsorbed onto the tunneling ...
Methods of electrically characterizing zinc selenide epitaxial layers on gallium arsenide substrates
(1994)
A number of different methods for electrically characterizing ZnSe thin films are presented. These include the Hall effect, current-voltage profiling, and capacitance-voltage profiling. The planar Schottky technique is ...
Towards a fullerene-based nanotechnology: The (10,10) tube
(1997)
While fullerenes form in yields exceeding 30% by mass when a laser generated pure carbon vapor is allowed to condense under annealing conditions, more than 70% of all vaporized carbon assembles in the form of single-wall ...
Spin-polarized metastable de-excitation spectroscopy: A new probe of alkali chemisorption on surfaces
(1991)
Metastable (Atom) De-excitation Spectroscopy (MDS) provides a powerful technique with which to investigate surface electronic structure with extreme surface specificity. In this technique a thermal energy beam of noble-gas ...
