Few electron double quantum dot in an isotopically purified ${}^{28}$Si quantum well

Andreas Wild, Johannes Kierig, Jürgen Sailer +5

We present a few electron double quantum dot (QD) device defined in an isotopically purified ${}^{28}$Si quantum well (QW). An electron mobility of $5.5\cdot 10^{4}c{m}^2(Vs{)}^{-1}$ is…
