Metal
Oxides
Metal-dielectric nanoparticle composites
and their linear-nonlinear optical
properties produced by selective
ion irradiation. Self-organized
nanodot formation on metal oxides
by high temperature ion irradiation.
Non-steady state radiation enhanced
diffusion of cations in metal oxides.
This work explores the use of mass
and energy selected ion beams for
surface modification, nanostructuring,
and metal quantum dot composites
for fast optical response due to
surface plasmon resonance.
Ion
Scattering
Development of
scattering and recoiling imaging
spectro-metry (SARIS) for surface
and adsorbate structure determinations.
Development of coincidence-correlation
techniques for interlinking of projectile
trajectory, collision site, impact
parameter, surface structure, recoiled
atom position, electronic charge
exchange. This work is crucial for
progress in ion/atom-surface interactions
such as heterogeneous catalysis,
plasma wall interactions, film deposition,
aeronautical and space engineering,
surface reactivity, and electron
density maps.
