Group Foci and Project List

The SAM in Sêr SAM stands for Sustainable Advanced Materials – that is to say future materials with advanced electronic or optoelectronic functionality that can be processed by low embodied energy methods and that contain earth abundant / low toxicity components. These materials are the focus of our primary research interests and include systems such as organic semiconductors, perovskites and new dielectrics that can be deposited at low temperature.

Our research and innovation activities also involve the development of new low energy manufacturing processes, particularly from solution. We are a combined experimental-simulation-theory research group and at a fundamental scientific level seek to establish robust structure-property relationships to both explain materials and device performance and characteristics, and guide rationale design of new systems. We have particular expertise in electro-optics – namely the physics of how light and electrical charge interact in materials particularly semiconductors. We make all of simulation tools such as transfer matrix analysis and optical constant determination available as open source on our Knowledge Sharing Portal.

Our main areas of application and technology interest include: next generation solar cells; photodetectors (both narrow and broad band); bioelectronics (that is the interfacing of electronic read-write systems with biological entities); light emitting diodes; and sensor platforms.

Sêr SAM is now part of a greater collective of cross-platform research activities in the Centre for Integrative Semiconductor Materials (CISM)] to be established in a new £30M device fabrication facility due for completion in early 2022. CISM is a futuristic concept focused on breaking down the silos of different semiconductor systems (silicon, compound, next generation, wide bandgap, low dimensional) to deliver new technology opportunities.

We hope you enjoy reading about our project portfolio.
