Colloidal Epitaxy

Event details

Epitaxy is defined as the growth of one crystalline substance on another so that both have the same crystalline structure and is an effect used in the manufacture of materials such as thin semiconductor films. For colloidal samples it has been found that periodically patterned surfaces will act as templates for crystalline growth in much the same way as is seen in epitaxy. How this process works and what colloidal crystalline structures form are discussed.

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
