Sustainable Compound Semiconductor Technology

2024 CDT student-led conference4

27th November 2024

Empowering Sustainable Technology Innovations

Compound semiconductors play a pivotal role in driving the sustainable technologies of tomorrow.

As the world transitions to renewable energy, more efficient electronics, and advanced telecommunications, compound semiconductors like GaAs, InP, and GaN offer unmatched performance in power electronics, optoelectronics, and high-frequency devices. Their superior efficiency in converting energy, whether through solar cells, LEDs, or power devices, reduces energy consumption and minimizes environmental impact.

The scalability of these materials through advanced fabrication methods ensures that future applications—such as electric vehicles, 5G networks, and facial recognition—will be built on a foundation of sustainability.

The SCST Conference serves as a platform for PhD students within the CDT for Compound Semiconductor Manufacturing to showcase their research and progress. Through presentations on innovative techniques, technological advancements, and the challenges they've encountered, the conference fosters collaboration and knowledge exchange.

With a focus on eco-friendly production methods and energy-efficient designs, this event highlights cutting-edge developments in the field, driving progress towards a greener, more sustainable future.
