Abstract
⺠Sub-10-nm domelike Ge QDs with uniform size were obtained directly on the Si(0 0 1) surface. ⺠Their density is the highest one among the Ge QDs grown directly on Si surface. ⺠Two metastate QDs, pyramid-to-dome and multiheaded dome, were observed due to no post-annealing. ⺠The QDs own a very strong non-phonon peak with a large blue shift of 0.19 eV at 14 K.
