The Slovenian innovator transforming microchip manufacturing
Data centres are the digital world's powerhouses – but they come with a heavy environmental cost. Globally, they consume an estimated 460 terawatt-hours (TWh) of electricity each year, equivalent to the energy needs of 153 million homes. Without intervention, their carbon footprint could reach 3.2% of global emissions by 2025. Teja Potočnik, a 26-year-old Slovenian researcher, is working to change that.
Her invention – an automated nanomaterial integration platform – optimises the manufacture of advanced semiconductor devices, otherwise known as chips. These advanced chips, in turn, power the servers and hardware that run today's data centres. By enabling the production of more energy-efficient chips, her innovation directly contributes to reducing the massive energy consumption of data centres worldwide.
'The problem we are solving is the ever-increasing demand for faster, more efficient and more powerful microchips. This is because of the demand of AI, quantum computing and data storage users', Potočnik explains, 'Our invention can help with the manufacture of more energy-efficient chips using nanomaterials, which means that there can be enormous energy savings.'
This pioneering project has earned her a place among the selected innovators honoured at the 2025 Young Inventors Prize, awarded by the European Patent Office.
As chips become smaller and more powerful, manufacturers are turning to materials like graphene, carbon nanotubes and quantum dots to push performance boundaries. But while these nanomaterials hold immense promise, integrating them at scale remains a major challenge.
Potočnik's invention, LithoTag, addresses that bottleneck. By embedding nanoscale markers into semiconductor wafers, the platform enables precise alignment and integration of nanomaterials with high repeatability. This bridges the gap between laboratory research and industrial manufacturing.
'The industry cares about reliability, replicability, and integration into manufacturing processes,' she says. 'No matter how good a technology is, it holds little value if it can't be scaled.'
Originally from Slovenia, Potočnik moved to the UK to study materials science and engineering, where she says she 'fell in love with nanomaterials'.
Potočnik co-founded the startup Nanomation while completing her PhD in nanofabrication at the University of Cambridge. With backing from Cambridge Enterprise, she and her team filed a patent application and began exploring commercial partnerships with chip manufacturers.
But it's not just about business: Potočnik's work directly supports the UN's Sustainable Development Goal 9 – Industry, Innovation and Infrastructure – by improving the scalability of sustainable microelectronics. It could lead to more energy-efficient consumer devices and data centre infrastructure, with widespread environmental benefits.
Looking ahead, Potočnik envisions her technology becoming standard in advanced electronics manufacturing. 'The real advantage of our technology is that it can be applied to any material and any sort of electronic design, so we really hope to become the industry standard in integrating nanomaterials into advanced circuits,' she explains.
Beyond the lab, the young Slovenian innovator hopes her story will encourage others to pursue bold, scalable ideas that can make a difference.
'To all the inventors who are thinking about realising their new idea, I would say just have an open mind and be brave,' Potočnik advises.
