The study of disorder and nanocrystallinity in C-S-H, supplementary cementitious materials and geopolymers using pair distribution function analysis
Akgül, Çağla; Monteiro, Paulo JM (2011-07-01)
Significant progress was achieved with the application of Rietveld method to characterize the crystalline phases in portland cement paste. However, to obtain detailed information on the amorphous or poorly crystalline phases, it is necessary to analyze the total scattering data. The pair distribution function (PDF) method has been successfully used in the study of liquids and amorphous solids. The method takes the Sine Fourier transform of the measured structure factor over a wide momentum transfer range, p...
The numerical study of pumping configurations on the lasing efficiency in photonic crystal fiber Raman laser
Berberoglu, Halil; Tarman, Işık Hakan (2013-01-01)
Cw Raman lasing characteristics of highly nonlinear photonic crystal fibers (PCF) are numerically investigated. The numerical approach is based on a pseudospectral algorithm developed earlier. Different pumping (forward, backward, and bidirectional) configurations are numerically simulated and the resultant efficiencies are shown to be the same under similar conditions. It is shown that the differences arise due to the pump being either single- or double-pass. (c) 2012 Elsevier GmbH. All rights reserved.

The investigation of quantum efficiency constituents of InAs/AlSb/GaSb based N structure type-II SL photodetectors with InAlAs interface
We report on the optical properties of InAs/AlSb/GaSb based Type-II superlattice N-structure with p on n configuration. The detector structure is designed to operate in the mid wavelength infrared range with 50% cut-off wavelength of 4.88 mu m at 79 K. Electronic properties of N-structure such as heavy hole-light hole splitting energies are optimized by a first principles approach taking into account InAlAs interface bonding between InAs/AlSb layers. A responsivity of 1.13 A/Wat 3.2 mu m was measured under ...
