Outline of Final Research Achievements

Strained Si/SiGe heterostructures were grown on Si(110) substrates using solid source molecular beam epitaxy. Relationship between crystalline/surface morphologies and hole mobility was investigated. One order of magnitude lower surface roughness than on those grown by gas source molecular beam epitaxy was revealed. As a result, hole mobility higher than 600 cm2/Vs was achieved in the strained Si layer.
