Low-dimensional materials have experienced a real revolution in both the technological and research fields recent decades [...]

13. ABSTRACT (Maximum 200 words) Prompted by the prediction of Cohen and coworkers that beta carbon nitride may have properties similar to diamond, there have been many attempts to synthesize this hypothetical metastable material. We successfully synthesized this material via epitaxial stabilization using TiN(lll) and ZrN(lll) as the growth template. The coatings were CN/TiN or CN/ZrN multilaye...

We have investigated features of liquid crystalline materials for organic polycrystalline field effect transistors (OFETs) with a model liquid crystalline material of 5,5”-dioctylterthiophene (8-TTP-8). Bulk mobility in polycrystalline thin films of 8-TTP-8 via its liquid crystalline phase was easily determined by time-of-flight experiments. Furthermore, we could evaluate impurity contamination...

New liquid-crystalline materials with a perhydroazulene core were synthesized and the stereochemistry of these compounds was investigated. The mesomorphic properties of the new LC compounds were investigated by differential scanning colorimetry, polarizing optical microscopy and X-ray diffraction. We report here on the LC properties of nonchiral materials, which predominantly exhibit smectic ph...

A fundamental imaging problem in microstructural analysis of metals is the reconstruction of local crystallographic orientations from X-ray diffraction measurements. This work deals with the computation of the 3D orientation distribution function for individual grains of the material in consideration. We present an iterative large-scale algorithm that uses preconditioned regularizing CGLS itera...
