2014 7th International Silicon-Germanium Technology and Device Meeting (ISTDM)

We achieved the world's first epitaxial growth of a Ge_1−x−ySn_xC_y layer, and investigated the effect of Sn incorporation on the growth of Ge_1−xC_x. Sn incorporation can decrease the epitaxial temperature of Ge_1−xC_x layer. Also, Sn incorporation can make C atoms stable at the substitutional site. This Ge_1−x−ySn_xC_y layer is expected to realize the energy band engineering independently on the lattice parameter...

In this paper, we propose a novel scheme for representing character string images in the scanned document. We converted conventional multi-dimensional descriptors into pseudo-codes which have a property that: if two vectors are near in the original space then encoded pseudo-codes are 'semi equivalent with high probability. For this conversion, we combined locality sensitive hashing (LSH) indices and...
