STM Atom Molecule Manipulation Movies of Hla Group

Shaping the future by controlling the atomic world...

We combine single atom/molecule manipulation schemes with a variety of tunneling spectroscopy measurements to investigate the physical, mechanical, electronic and chemical properties specific to the type of atoms or molecules on metallic surfaces. The innovative experiments are tailored to address several critical issues covering both fundamental understanding, and development of novel atom/molecule based nano-devices. Our focus research areas include molecular spintronics, nanobiotechnology, and the atomistic interactions on surfaces.
