We have studied the Ag/Ge( l l l )v r3 x v~ superstructure by grazing-incidence X-ray diffraction. In our structural analysis we find striking, similarities to the geometry of Au on Si(l l l) . The Ag atoms form trimer clusters with an Ag-Ag distance of 2.94 5:0.04 A with the centers of the trimers being located at the origins of the V~ x Vr3 lattice. The Ag layer is incomplete and at least one...
Let $G$ be a locally compact abelian group. The concept of a generalized multiresolution structure (GMS) in $L^2(G)$ is discussed which is a generalization of GMS in $L^2(mathbb{R})$. Basically a GMS in $L^2(G)$ consists of an increasing sequence of closed subspaces of $L^2(G)$ and a pseudoframe of translation type at each level. Also, the construction of affine frames for $L^2(G)$ bas...
Let $mathfrak{L}$ be the Virasoro-like algebra and $mathfrak{g}$ itsderived algebra, respectively. We investigate the structure of the Lie triplederivation algebra of $mathfrak{L}$ and $mathfrak{g}$. We provethat they are both isomorphic to $mathfrak{L}$, which provides twoexamples of invariance under triple derivation.
In this paper, a quantum well infrared photodetector based on cascade structure is proposed which is capable of simultaneous detection of two different wavelengths in mid-infrared region. The active region of this photodetector is monolithically sensitive to both wavelengths and the electron transport system is designed to transport electrons excited by two different wavelengths. By attachin...
