Applying transmission Kikuchi diffraction (TKD) allows us to fundamentally investigate the Si-doped-hafnium-oxide (HSO) microstructure that results from interface layer present in ferroelectric field-effect transistors. In addition predominant orthorhombic phase, dendritic HSO grains larger than 100 nm govern composition. Furthermore, observed strong out-of-plane texture aligned along [110] and...

In the trichalcogenide family of compounds Zr& " Hf " S3 there is a frequency range where the optic modes are expected to be describable by a simple one-dimensional model. It is shown that the disorder-induced linewidth in the relevant frequency range could be consistent with theoretical calculations for a simple diatomic chain model. The vibrations involved are along the chain direction and ar...

Recently, we showed that titanocene silyls are much more stable with Ti in the oxidation state +3. The current study demonstrates that analogous Zr and Hf compounds can also be obtained by reaction of a suitable metalate precursor with an oligosilanyl dianion. As the obtained complexes formally possess a d(1) electron configuration, they were investigated using EPR spectroscopy. The correspondi...
