We present a few electron double quantum dot device defined in an isotopically purified 28Si quantum well (QW). An electron mobility of 5.5·104cm2(Vs)-1 is observed in the QW, which is the highest mobility ever reported for a two-dimensional electron system in 28Si. The residual concentration of 29Si nuclei in the 28Si QW is lower than 103ppm, at the verge where the hyperfine interaction is ...
