A high-throughput thin film methodology based on combining molecular beam epitaxy (MBE) atomic sources which can be combined with a high intensity plasma atom source is described. Compositional gradients of both amorphous and crystalline materials including alloys (phase change memory), oxides (functional ceramics), hydrides (hydrogen storage), ion conductors (lithium ion batteries) and crystalline sulphides (Photovoltaics) will be presented to demonstrate the versatility and advantages of the synthetic approach. The scalability of the synthesis to on chip screening methodology will be highlighted, as well as the necessary characterisation and informatics components of the overall workflow. A more detailed description of how this high throughput method has been applied will be exemplified in the synthesis and screening of alloy and supported particle electrocatalyst libraries. This will emphasize both the importance of being able to synthesize non noble alloys and materials such as carbides, but also the importance of substrate variation and particle size, both of which can critically influence catalyst activity and stability.
