Valence Band Spectroscopy in V-grooved Quantum Wires Typeset Using Revt E X
نویسندگان
چکیده
We present a combined theoretical and experimental study of the anisotropy in the optical absorption of V-shaped quantum wires. By means of realistic band structure calculations for these structures, we show that detailed information on the heavy-and light-hole states can be singled out from the anisotropy spectra independently of the electron confinement, thus allowing accurate valence band spectroscopy.

X-ray Photoemission Study of Nis 2−x Se X (x = 0.0 -1.2) Typeset Using Revt E X 1
Electronic structure of NiS2−xSex system has been investigated for various compositions (x) using x-ray photoemission spectroscopy. An analysis of the core level as well as the valence band spectra of NiS2 in conjunction with many-body cluster calculations provides a quantitative description of the electronic structure of this compound. With increasing Se content, the on-site Coulomb correlatio...

We present a theoretical investigation of the electronic and optical properties of V-and T-shaped quantum wires. Valence band mixing as well as realistic sample geometries are fully included through an accurate and efficient approach that is described here in detail. We investigate the resulting valence band structure, which shows some significant peculiarities, such as an anomalously large spi...
متن کاملElectronic Structure of Nis 1−x Se X Typeset Using Revt E X 1
We investigate the electronic structure of the metallic NiS1−xSex system using various electron spectroscopic techniques. The band structure results do not describe the details of the spectral features in the experimental spectrum, even for this paramagnetic metallic phase. However, a parameterized manybody multi-band model is found to be successful in describing the Ni 2p core level and valenc...
متن کاملFrom Surface to Random Criticality in Layered Planar Ising Models. Typeset Using Revt E X
A general case of a spatially nonuniform planar layered Ising model, or an equivalent quantum Ising chain, is analysed with an exact functional real space renormalization group. Various surface, finite size, quasiperiodic and random layer (McCoy-Wu) universality classes are obtained and discussed within a single theoretical framework leading to new insights into the nature of random criticality...
متن کاملTransport in Random Quantum Dot Superlattices Typeset Using Revt E X 1
We present a novel model to calculate single-electron states in random quantum dot superlattices made of wide-gap semiconductors. The source of disorder comes from the random arrangement of the quantum dots (configu-rational disorder) as well as spatial inhomogeneities of their shape (morphological disorder). Both types of disorder break translational symmetry and prevent the formation of minib...
