Chemical vapour deposition of group 14 chalcogenides
Lead Research Organisation:
University of Southampton
Department Name: Sch of Chemistry
Abstract
This project will develop new CVD reagents for growth of thin film tin sulfide and related semiconductors, with a focus on controlled multilayer deposition to enhance thermoelectric performance in energy generation and recovery. The student will also take an active involvement in depositions using ALD during their placements at the company.
We have deposited tin sulfides and selenides from SnCl4 complexes with thio-/seleno-ethers (Dalton Trans. (2007),4769; Chem. Mater. 24,(2012),4442; and unpublished work), with deposition of SnE or SnE2 determined by the substrate temperature during deposition. Initially, this project will investigate temperature variation as a strategy for SnS/SnS2 multilayer production from related precursors. The effect of other deposition conditions will be examined in more detail to control the film thickness and crystallite size/orientation.

| Description | The development of a number of single source precursors for the low pressure chemical vapour deposition for a variety of materials that are of interest for thermoelectric and optoelectric applications. A variety of materials have been deposited and fully characterised proving the processes successful. |
| Exploitation Route | The use of the processes of material deposition could be further developed for the fabrication of thermoelectric devices or other electronic devices. |
