Paragraf unveils solution to cut data center and AI chip power use

Paragraf Limited is advancing its production capabilities in 2D materials to address the rising energy consumption in data centers and AI chips. The company, known for its expertise in graphene, is now producing molybdenum disulphide (MoS₂), a 2D semiconductor that promises significantly lower power usage in electronic devices.

Paragraf is a key industrial partner in a £6.4 million research program funded by the Engineering and Physical Sciences Research Council (EPSRC). The initiative, titled “Enabling Net Zero and the AI Revolution with Ultra-Low Energy 2D Materials and Devices” (NEED2D), aims to reduce the energy demands of data centers and high-performance computing. The program involves collaboration with Queen Mary University of London and 22 industrial partners across the supply chain.

The growth of artificial intelligence has led to increased energy consumption in data centers. Traditionally, the solution has been to expand generating capacity, but this program seeks to reduce energy demand at the source. The inefficiency of silicon transistors, which lose a significant amount of energy as heat, is a key factor in this consumption.

Molybdenum disulphide offers a more efficient alternative. As a semiconductor, MoS₂ can be integrated with existing silicon structures or used independently. Its thin structure allows for a high on/off current ratio and low leakage current, making it highly power-efficient. The program targets devices that consume up to 90% less energy than conventional silicon-based devices.

Paragraf will supply high-quality, large-area MoS₂ for the research, leveraging its expertise in wafer-scale graphene production. The company will collaborate closely with Queen Mary University of London on device research. Dr. Simon Thomas, CEO and Co-Founder of Paragraf, emphasized the importance of this research in advancing the UK's capabilities in next-generation computing materials.

Professor Sir Colin Humphreys of Queen Mary University of London, the project lead, highlighted the potential of 2D materials like MoS₂ to succeed silicon in electronics. Paragraf's demonstrated ability to produce high-quality MoS₂ at scale is a crucial step in developing more energy-efficient technologies.

The program encompasses all stages from material to device, including precursor chemicals, growth equipment, and end users. This comprehensive approach ensures a direct path to industrial application, supported by UK chemical suppliers, equipment manufacturers, and technology companies.
