The results indicate unambiguously that the chain stiffness of siloxanes governs the degree of ordering in the restricted geometry of the interfacial region.
Upon AFM measurements, Goodfellow Ti substrates (99.99% purity), yielded the smoothest surface and the highest degree of ordering from all substrates.
Poly 9,9-dihexylfluorene) exhibits an additional degree of ordering in the Poly 9,9-dihexylfluorenewhich is likexhibitsrise from hexanonadditionalg of the backbone chains.
The degree of ordering at the Al2O3 Al interface at 750 °C was quantified and both layering and in-plane ordering were found.
The model makes use of thermodynamic data to evaluate the thermodynamic factor as well as the degree of ordering at a given temperature.
Surface modified substrates coupled with vibration during the deposition resulted in a higher degree of ordering over a large deposition area.
However, the degree of ordering was poor with fringe stacking occurring for ∼20% for the fringes, with a mean of 2.11 fringes.
In addition, the degree of ordering attained following a 1 h heat treatment at 2400 °C also decreased with increasing PVC content.
Transmission electron microscope (TEM) and X-ray diffraction (XRD) analysis showed the existence of ordered graphite phase in this mostly amorphous titanium carbide derived carbon (TiC-CDC), and the degree of ordering increased with chlorination temperature.
This was apparent from the luminescence results, where more than 6 quite narrow luminescence bands were found, and also from the RBS/channeling analysis which showed, that the doped structure has similar degree of ordering as the bulk crystal LiNbO3.
Experimental results are analyzed within the context of a model that considers the force balance on dislocations on the two competing glide planes as a function of the degree of ordering.
