We report a low-energy electron microscopy study of novel bamboo-like (quasi-one-dimensional) growth during deposition of Ag on Si(001) surfaces at elevated temperatures. The bamboo crystals, with typical dimensions of 10 μm in length and varied height and width (tens to hundred of nanometers), align primarily along Si[110] or Si[1−10] orientation. Low-energy electron microscopy imaging further demonstrates...
The growth of Cu on Si(111) surface with and without hydrogen termination was studied with low energy electron microscopy. On the clean surface the two-dimensional “5×5” incommensurate layer is first formed followed by the formation of three-dimensional (3D) islands. On the hydrogen-terminated surface the formation of the “5×5” structure is suppressed and nano-scale 3D islands decorate the steps and...
