| Description | We aimed to develop new methods of detecting THz light with silicon electronics. We have succeeded in producing new detectors based on regular dopants with unprecedented speed (in the GHz range). We developed a goon understanding of how those devices work, and the microscopic processes that govern the speed and wavelength range. The work is in collaboration with University College London who developed electrical detection of spin resonance, and Peking University in China who made the devices. |
| Exploitation Route | These new THz detectors are likely to find many applications in quantum technologies, security applications, bio-molecule detection for chemicals etc. |
| Sectors | Aerospace, Defence and Marine,Chemicals,Electronics,Manufacturing, including Industrial Biotechology,Pharmaceuticals and Medical Biotechnology |

| Description | UK - China partnership on silicon spintronics |
| Organisation | Peking University |
| Country | China |
| Sector | Academic/University |
| PI Contribution | The project was the beginning of a very successful collaboration between two UK groups (Surrey and UCL), and a new partnership with a Chinese team (Peking University). Surrey brings expertise in THz optics and spin dynamics in semiconductors, UCL in magnetism and magnetic resonance, and Peking in CMOS and MEMS technologies for silicon devices. Bringing this team together enabled (and enables) new devices for laser controlled spintronic and orbitronic devices in silicon with electrical readout. The PKU team is a world leader in silicon nanoscale device engineering, and shares a long-standing interest in infrared technology with the UK groups. Achievements include a cantilever- based IR detector and monolithic integration with industry standard microelectronic (CMOS) circuits on Silicon On Insulator wafers. These wafers and processing are hard to source at low cost for academic research outside of China. PKU contributed SOI wafers, processing, and academic, technical and student time. |
