An examination is done on the extended Cauchy equations, which are derived, based on the Vuks equation for describing the wavelength- temperature-dependent refractive indices of liquid crystal compounds and mixtures. In conclusion, correlations between the Cauchy coefficients for the nematic and isotropic phases are derived and validated by the experiments.

Research is done on thermally driven transport and exchange of hydrogen and deuterium in silicon-based metal-oxide-semiconductor (MOS) device-related structures, which were experimentally, examined using elastic recoil detection analysis. In conclusion, isotope exchange in the polycrystalline Si/SiO2 structure was noticed above 450 degrees C, BPSG revealed very little relative isotope exchange and implications to MOS device processing is examined.

An examination is done of anisotropic optical properties of vacuum-deposited thin films of high-efficiency blue-emitting ter(9,9-diarylfluorene)s using variable-angle spectroscopic ellipsometry. It is inferred that the vacuum-deposited ter(9,9-diarylfluorene) molecules tend to align their molecular axes and pi-pi* transition dipole moments along the substrate surface as noticed in spin-coated films of alkyl-substituted polyfluorenes or oligofluorenes, even though the present ter (9,9-diarylfluorene)s have rigid and bulky aryl substituents on C9, relatively shorter oligomer chains, and very different deposition conditions.

The carrier-transport properties of amorphous ter(9,9-diarylfluorene)s are reported. The unusual nondispersive ambipolar carrier transport and high electron mobility is observed for these molecular materials.

A convergent synthesis, the single-crystal structure and intriguing properties of novel ter(9,9-dairylfluorene)s are reported. Ter(9,9-diarylfluorene)s that contains intrinsically stronger Csp(super 3) -Csp(super 2) bonds between the pendant aryl groups and the C9 carbon of fluorene exhibit excellent morphological and thermal stability.
