WebThe pattern of reactive and non-reactive scattering was determined by STM. These collimated surface-molecular-beams have the potential to aim molecular projectiles with selected impact parameters at the many target species identifiable at a surface by STM. WebIn the molecular beam epitaxy technique, layers are grown by directing an atomic or molecular beam onto a heated substrate located in an ultrahigh-vacuum environment. The particles in the molecular beam adhere to the substrate, resulting in a lattice-matched layer.
