Enriched 28Si is a critical material for solid state QI due to long quantum coherence times (T2) as measured by bulk ESR and NMR studies. The enriched silicon allows coherence times that exceed minutes and also results in substantially reduced optical line widths. Following these ensemble measurements, single electron devices fabricated in enriched silicon have been shown to have impressive coherence times, as well. In this project, we have demonstrated the ability to produce crystalline thin films of 28Si enriched to >99.9999% from natural abundance silane. We are depositing this silicon onto natural silicon substrates to grow epitaxial films for use in fabrication of quantum devices. Our work to fabricate quantum devices from the enriched silicon includes conventional electron beam lithography, STM hydrogen lithography and collaborative research.
