"The completion of the proposed research will contribute to a better understanding of novel kinetic pathways and growth modes of metal adatoms deposited on metal and semiconductor surfaces driven by surface diffusion, especially at low temperatures. This is one of the important challenges in nanotechnology i.e. to discover ways where nanostructures of controllable geometry and dimensions can be easily fabricated. So far the Pb/Si system has been the prototype where all the results obtained have been reproduced by several groups with different techniques. The knowledge gained has identified that energetics are equally important as kinetics. We plan to search for other metal systems where they have more relevance to reactivity and where similar height control is possible. We will study height and geometry dependent variations of reactivity during oxygen and hydrogen adsoption on the nano-islands as a result of QSE starting first with Pb islands."@en .
