Design rules for dislocation filters
Description | My part in this work was to understand the defects that prevent materials with different properties from being combined effectively and find ways to control them. By designing layers of material with different internal strains, these defects can be made to combine and annihilate, producing high quality material. |
Exploitation Route | Ideally we would like to be able to combine, for example, GaAs with silicon, leading to new types of computer chips that communicate using light rather than electricity. |
