  • Abstract
    We have grown Si/SiGe modulation doped quantum wells by gas source molecular beam epitaxy using, for the first time, arsenic as an n-type dopant. The layers are characterised by magnetotransport measurements and SIMS analysis. The latter shows an arsenic concentration in excess of 1019 cm¿3 along with strong surface segregation.
