German scientists create material that never existed before and could transform semiconductors, lasers, and quantum technology

Researchers in Germany have successfully created a material that has never existed before, a stable alloy made from carbon, silicon, germanium, and tin. This new compound, known as CSiGeSn , is being hailed as a potential game-changer for the future of electronics, optics, and quantum computing . The team behind the discovery includes scientists from Forschungszentrum Jülich and the Leibniz Institute for Innovative Microelectronics (IHP). For years, combining these four Group IV elements into a single, stable crystal lattice was considered virtually impossible due to their vastly different atomic sizes and bonding behaviors.

'By combining these four elements, we've achieved what many thought wasn't possible, the ultimate Group IV semiconductor,' Buca said. 'This opens up a range of new applications, from lasers and photodetectors to quantum circuits and thermoelectric energy devices.' by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 걷기 대신 이 운동, 매일 5분하면 "강철무릎" 될 수 있습니다. 큰딸민지 더 알아보기 Undo Carbon atoms are extremely small and bond very differently compared to the much larger tin atoms, making their integration in a single material extremely challenging. But through precise engineering and the use of a chemical vapor deposition (CVD) system from German equipment manufacturer AIXTRON, the team managed to overcome these physical limitations and create a uniform, high-quality material. Boosting the chip manufacturing technologies Live Events The new material is expected to be fully compatible with existing chip nufacturing technology, particularly the widely used CMOS process. According to the researchers, this compatibility is crucial because it allows advanced new components to be produced using current semiconductor infrastructure, removing one of the biggest barriers to commercialization. Carbon is the game changer The addition of carbon takes the possibilities even further, allowing unprecedented control over a property called the band gap, the key factor that determines how a material behaves in electronic and optical applications. With this fine-tuning, devices such as room-temperature lasers, energy-harvesting thermoelectrics, and highly sensitive optical sensors could become not only possible, but scalable. Prof. Dr. Giovanni Capellini from IHP, who has been working with Buca for more than a decade on new semiconductor materials, emphasized the potential of the discovery. 'The material offers a unique combination of tunable optical properties and full silicon compatibility,' Capellini said. 'This lays the foundation for scalable photonic, thermoelectric, and quantum components.' The significance of the discovery extends beyond the lab. Because the alloy was created using tools and processes already standard in the chip industry, there is strong potential for scaling up production and deploying it in commercial applications sooner rather than later.
