Multi-plume Pulsed Laser Deposition for Advanced 3-d Micro-structuring (MULTIPLE)

Lead Research Organisation: University of Southampton
Department Name: Optoelectronics Research Centre

Abstract

The research programme is intended to show that we can use Pulsed Laser Deposition, which is a physical vapour transport technique, to grow essentially any structure in thin film format, using three separate laser-generated plasma plumes. We will use three laser sources, directed to three target materials, which can be of arbitrary composition, stoichiometry, and format. The plumes are then incident on a substrate which will receive the directed plasma plumes, to allow a thin film to grow in the desired geometry, composition and format.The flexibility of having these three targets is in some ways equivalent to the use of the three primary colours to construct any subsequent colour imaginable, as in a colour chart. Mixing of plumes, both in time and space, will enable uniquely complicated materials to be grown. This colour analogy goes further however in that we will now be able to 'paint' arbitrary compositions of materials onto substrates in the same way that artists will colour mix and then paint onto a canvas. New thin film geometries will be readily grown, and the intention in this programme is to explore in detail what is possible, what is desirable and useful, and what, though desirable, cannot be grown. Once we have this knowledge, then all growth geometries that we have achieved will be assessed for their application in practical and useful optical device technologies.

Description For the first time, as evidenced from our findings, we have shown that the technique of Pulsed Laser Deposition can be implemented with multiple targets and multiple lasers, thereby making the technique much more useful and versatile for the community of material scientists that use laser deposition
Exploitation Route Following our work, scientists and technicians involved in the growth of designer thin films can now benefit from our results using multiple lasers and target, as materials can be grown to a precise and detailed recipe
