Admittance Analysis of Thermally Evaporated Hole Selective MoO3 on Crystalline Silicon
Ahiboz, Doğuşcan; Nasser, Hısham; Turan, Raşit (null; 2016-11-14)
Integration of stoichiometric molybdenum trioxide (MoO 3-x ) as an effective hole transport layer (HTL) in solar cells is expected to reduce fabrication cost by eliminating the high temperature processes while maintaining high conversion efficiency. In this work we performed a systematic study to extract the electronic properties of vapor-phase deposited MoO 3-x thin film and MoO 3-x /crystalline silicon interface through capacitance and conductance analysis. Effect of MoO 3-x thickness as well as post depo...
Hydration and properties of limestone incorporated cementitious systems
Erdoğdu, Korhan; Tokyay, Mustafa; Department of Civil Engineering (2002)
As limestone is a new widely used mineral addition in cement, understanding the effects of this material on cement properties and hydration in a detailed manner is of substantial importance for efficient and proper usage. Consequently, the current study is designed. In the experiemental study, three different limestones were used. The aim of using different limestones is to reach broad generalisations by crosschecking the results and compare the effects of limestones with different structures. These limesto...
Admittance analysis of an MIS structure made with PECVD deposited a-SiNx : H thin films
Atilgan, I; Ozder, S; Ozdemir, O; Katircioglu, B (Elsevier BV, 1999-07-01)
a-SiNx:H thin films, prepared by the PECVD technique, were optically and electrically characterized. The frequency dependent trap admittance derived for the MIS structure in the accumulation gate voltage regime was revised. Based on these results an omitted multiplying factor was included into the derivation. An extension of the tunnelling model in the depletion bias regime was used in comparison with the widely accepted statistical model and finally, the more general feature of the tunnelling-based approac...
Hydration of alinite cement produced from soda waste sludge
Ucal, Gultekin Ozan; Mahyar, Mandi; Tokyay, Mustafa (2018-03-10)
Alinite cement is an alternative inorganic, low-energy binding material. This experimental study investigated hydration characteristics of alinite cement which was produced by using soda waste sludge as a raw material. Paste microstructures were studied by X-ray powder diffraction and scanning electron microscopy. Heat of hydration and compressive strength values were also determined. Formation of C-S-H gel and calcium chloroaluminate hydrates which resemble Friedel's salt was observed. Induction period of ...
Demineralization of Sirnak asphaltites by flotation
Hicyilmaz, C.; Altun, Naci Emre (2006-01-01)
Demineralization of Sirnak asphaltite by flotation method was investigated. The effect of different parameters on the process such as particle size, collector type and amount, pH, pulp density, flotation time and cleaning of rougher flotation product was studied. Treatment with collector Accoal 18 (Cytec Ind. Inc.) at natural pH gave the highest recovery of combustibles and low ash yield. Flotation at pulp density 10% solid by weight and 2-min residence time gave the best result. As a result of single-stage...
