Techniques such as cryo-electronmicroscopy can be used to determine the
shape of the ground state of large molecules and nanostructures. In this
talk, I will discuss recent advances to obtain sub-nanometer spatial
resolution images of
excited states by using laser-assisted STM. We can visualize exciton
localization in carbon nanotubes, image the effect of defects on orbital
shape in quantum dots, and visualize energy and charge transfer. 3-D
information about excited states of individual
quantum dots can be obtained by rolling them on a substrate. In
addition, we can use the STM to take movies of cooperative glass regions
(glassy nanoclusters) hopping on glass surfaces such as SiO2, amorphous
silicon, or metallic glasses. It is now possible
to map out the energy landscapes for the cooperative nanoscale motion
on glasses.
