Archer Materials (ASX:AXE), a semiconductor company advancing the quantum technology and medical diagnostics industries, has developed a highly manufacturable carbon film with attractive quantum properties including long room-temperature electron spin lifetimes.
- Developed new carbon films with electron spin lifetimes exceeding those previously measured on carbon nano-onions.
- The films are produced with a proprietary chemical vapour deposition process. The process should be scalable to full wafers.
- The films can be processed into quantum devices using standard semiconductor fabrication techniques, overcoming the manufacturing roadblock for carbon nano-onions (CNOs).
- In addition to electron spin lifetime measurements, testing is in progress to observe other key quantum properties required to build quantum devices. We expect to accelerate this compared with our efforts on CNOs.
- The electron spin properties combined with the manufacturability opens a path to using the carbon material in a wide variety of applications like extremely sensitive magnetometers or in the biotechnology field, in addition to quantum computing.
- Experimental work and theory collaboration with École Polytechnique Fédérale de Lausanne (EPFL) has resulted in further fundamental understanding of our carbon materials. A scientific paper of the findings will be submitted for review and publication in the coming weeks.
Greg English, Executive Chair of Archer, said, “Manufacturability of many quantum materials is an ongoing challenge in the field, as this can also hinder research and development. This new carbon film helps accelerate the manufacturability of the qubit material. Working on this new film, alongside CNOs or even in place of CNOs, will accelerate development of our quantum technology and provides a means of volume manufacturing of such devices. By observing quantum phenomena sooner, we can eventually develop quantum devices more rapidly.”
