Dual emissions from MnS clusters confined in the sodalite nanocage of a chalcogenide-based semiconductor zeolite.
A new host-guest hybrid system with MnS clusters confined in a chalcogenide-based semiconductor zeolite was for the first time constructed and its photoluminescence (PL) properties were also investigated. The existence of MnS clusters in the nanopores of the semiconductor zeolite was revealed by UV-Vis absorption spectroscopy, steady-state fluorescence analysis, Raman as well as Fourier transfo...
متن کاملModeling and Simulation of Strained Quantum Wells in Semiconductor Lasers
Amodel allowing for efficiently obtaining band structure information on semiconductor Quantum Well structures will be demonstrated which is based on matrix-valued kp-Schrödinger operators. Effects such as confinement, band mixing, spin-orbit interaction and strain can be treated consistently. The impact of prominent Coulomb effects can be calculated by including the Hartree interaction via the ...
متن کاملPredicting the Properties of Semiconductor Clusters
The electronic and structural properties of semiconductor clusters are examined using pseudopotentials and a real space method. Examples of this method are applied to predict the photoemission spectra, the vibrational modes, and the polarizabilities of Si and Ge clusters.
متن کاملStructure and bonding of small semiconductor clusters.
We calculate the geometrical and electronic structure of small Sin, Sin +, and Sin clusters up to sites n = 14 within a combined tight-binding-density-functional-theory scheme. Especially stable structures for n = 6 and 10 coincide with observed abundancies in the experimental mass spectra. All equilibrium structures are found to be close packed, with a different bonding than found in the bulk ...
متن کاملThree-dimensionally Confined Diluted Magnetic Semiconductor Clusters
We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters o f 2 5 A diameter are successfully synthesized inside a glass matrix and fully characterized by chemical analysis, x-ray diffraction, extended x-ray absorption fine structure (EXAFS), and photoluminescence spectroscopy. Effect of size quantization on t...
