Characterization of cds thin films and schottky barrier diodes
Korkmaz, Sibel; Erçelebi, Ayşe Çiğdem; Department of Physics (2005)
CdS thin films were deposited by thermal evaporation method onto glass substrates without any doping. As a result of the structural and electrical investigation it was found that CdS thin films were of the polycrystalline structure and n-type; and of the transmission analysis optical band gap was found to be around 2.4 eV. Temperature dependent conductivity measurements were carried out in the range of 180 K ا 400 K. The dominant conduction mechanism is identified as tunnelling between 180 K ا 230 K and the...
Characterization of electromagnetic wave absorbing properties of sic-based and alumina ceramic woven fabrics
Tan, Elvan; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2008)
Electromagnetic wave absorbing properties of SiC-based and alumina ceramic woven fabrics have been investigated. Electrical conductivities of SiC-based ceramic woven fabrics were modified by heat treatment in air resulting in their oxidation. Surface properties of alumina woven fabrics were altered by gold-sputtering resulting in a high conductivity layer on the surface of the wovens. Electromagnetic wave interactions of single layer and double layered combinations of these ceramic woven fabrics were determ...
Characterization of non-Fickian moisture absorption in thermosetting polymers
Güloğlu, Görkem Eğemen; Altan, M. Cengiz (2015-05-22)
© 2015 AIP Publishing LLC.A recently developed moisture absorption model for thermosetting polymers that combines the non-Fickian, diffusion hindrance effects and three-dimensional anisotropy is introduced. The hindered diffusion model is shown to predict both short term Fickian and long term anomalous moisture absorption behavior often observed in thermosetting polymers and their composites. The salient characteristics of long term moisture uptake such as the equilibrium moisture content and the effect of ...

The GUNAM-ODAK research group is developing Thermal Energy Storage (TES) technologies for Concentrated Solar Power systems. Focus is on solid-particle (granular) TES materials such as silica sand due to their high melting temperatures and low costs. In the proposed work, the experimental equipment needed to characterize some of the most important properties of TES materials will be constructed, with the goal of characterizing new materials and providing accurate inputs for numerical modeling. Specifically, ...
