Electrodeposition from weakly coordinating solvents

Lead Research Organisation: University of Southampton
Department Name: School of Chemistry


Studies of the electrochemical deposition of p-block elements and their alloys for applications in thermoelectrics, memory and infra-red detectors. Studies will involve the use of both conventional non-aqueous solvents, such as dichloromethane, and of supercritical fluids and the characterisation of the composition and properties of the deposits using a range of techniques.

Description This project is concerned with the electrodeposition of p-block elements for the manufacture of semiconductors, and the role of the solvent in this process. For electrodeposition, the element/s to be deposited must first be dissolved in a solvent. The nature of the solute and solvent can dramatically alter the interactions between the two, therefore judicious choice of the solvent is necessary to achieve the desired behaviour of the metal precursors to be deposited. The project is associated with the Advanced Devices by Electroplating (ADEPT) program grant which intends to electrodeposit functional semiconductor devices. The project aims to understand the influence the solvent has on the behaviour of the elements of interest and discover solvents for use in the project superior to those originally proposed. To this end, several additional solvents have been identified and demonstrated to be appropriate for electrodeposition. Some are also capable of performing electrodeposition at raised temperatures, which is currently not possible on the ADEPT grant and is highly desirable since doing so typically improves the material properties of the deposited material.
Exploitation Route As stated above, new solvents have been selected for investigation. These have the potential to significantly improve the capabilities of the ADEPT grant, or others interested in similar materials by permitting the electrodeposition at raised temperatures. It is also expected that semiconductors which were previously unsuccessfully deposited become possible to do so in the new solvents (for reasons presently under investigation), providing new capabilities to the ADEPT grant and wider material science field.
