Direct correlation of crystal structure and optical properties in wurtzite/zinc-blende GaAs nanowire heterostructures
Direct correlation of crystal structure optical properties
2010/11/25
A novel method for the direct correlation at the nanoscale of structural and optical properties
of single GaAs nanowires is reported. Nanowires consisting of 100% wurtzite and nanowires presenting zi...
Optical Properties of (SrMnO3)n/(LaMnO3)2n superlattices: an insulator-to-metal transition observed in the absence of disorder
Optical Properties insulator-to-metal transition absence of disorder
2010/11/23
We measure the optical conductivity 1(!) of (SrMnO3)n/(LaMnO3)2n superlattices (SL) for
n = 1, 3, 5, and 8 and 10 < T < 400 K. Data show a T -dependent insulator to metal transition
(IMT) for n 3...
Magnetic and Optical properties of strained films of multiferroic GdMnO3
Magnetic Optical properties of strained films multiferroic GdMnO3
2010/11/24
The effects of strain on a film of mulitferroic GdMnO3 are investigated using both
magnetometry and magneto-optic spectroscopy. Optical spectra, in the energy range 1.5eV -
3.5eV, were taken in Fara...
Optical Properties and Determination of Thermal Transformation Parameters for Se0.65Te0.35 High Reflectance Thin Films
Optical Properties and Parameters High Reflectance Chalcogenide Semiconductors Thermal Transformation Parameters
2010/4/9
Chalcogenide glasses Se-Te have been prepared from the high purity constituent elements. Thin films of these materials have been deposited by vacuum evaporation. The thickness effects on the optical p...
Influence of the Current Density and Resistivity on the Optical Properties of P-Type Porous Silicon Thin Films Fabricated by the Electrochemical Anodizing Method
Porous silicon Photoluminescence Optical properties Reflectance Optical absorption
2010/9/29
Porous Silicon thin films were produced in this work by the electrochemical anodizing method. The samples were fabricated anodizing p type Si substrates with different resistivities in hydrofluoric ac...
