Semiconductor developer Archer Materials (ASX: AXE) has manufactured a new carbon film with electron spin lifetimes exceeding those previously measured in
carbon nano-onions (CNOs). The film was developed as part of the company's ongoing work with academic researchers at the University of New South Wales to create a scale-up path and manufacturable methods for CNOs. Archer expects to be able to observe key quantum phenomena on the films sooner than with CNOs and eventually develop quantum devices more rapidly. Standard techniques The new film is produced using a proprietary chemical vapour depositing methodology and can be processed into quantum devices using standard semiconductor fabrication techniques, thereby overcoming the manufacturing roadblock for CNOs. The clean process ensures films have extremely low or controlled…
