Abstract:

This proposal is aimed at investigating the influence of substrate steps on molecular beam epitaxial growth of Bi2Se3 and Bi2Te3 topological insulators on Si 111. It uses a novel combinatorial approach by creating micro-lens structures on Si111 substrate. The microlens contains a combination of numerous micro-surfaces with different miscut angles and miscut orientation. By using scanning probe microscopy, we can investigate how different miscut angles and orientations influence the growth process.
