Metaloxide Pulsed Laser Deposition

Hydrogen generation by direct water splitting with solar radiation is a possibility to provide cost-effective, clean, sustainable fuels facilitating our society the long-term shift away from fossil energy.In order to achieve solar-to-hydrogen conversion efficiencies above 15%, which are required for an industrial application of this technology, new chemically-stable semiconductors have to be developed and optimized.

Multinary metal oxide and metal oxynitride materials are promising materials classes that are abundant and with good chemical stability.

To accelerate the discovery and optimization of these materials classes, we aim for a high-throughput approach in which high-quality thin film material, tunable in composition, thickness, and/or dopant gradient are deposited by pulsed laser deposition (PLD).

A state-of-the-art pulsed laser deposition tool for combinatorial materials for the development of metal-oxy-nitride based catalyst will be coupled to the UHV analysis systems at EMIL to allow immediate, fast, and comprehensive characterization of the materials.
