Description
The bubbles form when aluminum was deposited on a thin flake of topological insulators (TI) BiSbTeSe by thermal evaporation. TI is a kind of material which is conducting on the surface but insulating in interior. Aluminum is a common metal in daily life but actually superconducts at low temperature (-270 degC). The study of the interface between aluminum and TI helps develop the understanding of some fundamental questions in condensed matter physics and more well-known field quantum computing. Obtaining flat and clean interface between aluminum and TI is critical in experiments. We found that the bubbles only form with liquid nitrogen cooling (-100 degC) during the evaporation, which destroys the sample but has its own beauty as art in science.
