Mol.-dynamics simulations of structural relaxation in electronically excited NO-doped solid neon are presented. The NO impurity is excited to its lowest A (3ss) Rydberg state, inducing a rearrangement of the surrounding medium in the form of a bubble, due ...
Combinatorial lithium niobate deposition on 150 mm naturally oxidized silicon (100) wafers in a high-vacuum chemical vapor deposition reactor using Li(OBut) and Nb(OEt)4(dmae) is presented. The novel precursor supply system allows individual spatial contro ...
In this thesis, the magnetic properties of self-assembled 3d and 4d metal nano-structures supported on surfaces have been investigated. The atomic coordination within the nano-structures was found to profoundly affect important quantities such as the magne ...
We have investigated by angle-resolved photoemission spectroscopy changes induced by Xe adsorption on the spin-orbit-split bands of the epitaxial Ag(111) (root 3x root 3)R30 degrees-Bi surface alloy. We observe an extensive backfolding of the alloy band st ...
Nowadays, gold compounds constitute a family of very promising experimental agents for cancer treatment. Indeed, several gold(I) and gold(III) compounds were shown to manifest outstanding antiproliferative properties in vitro against selected human tumor c ...
We report the 87Rb NMR results in a recently synthesized Na5RbCu4(AsO4)Cl2. This complex novel two-dimensional (2D) cuprate is an unique magnetic material, which contains layers of coupled Cu4O4 tetramers. In zero applied magnetic field, it orders antiferr ...
Results of present and previous measurements of the23Na NMR response, dc- and ac-magnetic susceptibilities and the specific heat ofNa2V3O7at low temperatures suggest that this material is close to a quantum critical point (QCP) atm0H¼0 T. The experimental ...
The reproducible synthesis of the unusual ionic aluminum compd. [Tl3F2Al(OR)3]+[Al(OR)4]- (1) is reported. In the reaction of Li[Al(OR)4] [R = C(H)(CF3)2] with TlF the initially desired Tl[Al(OR)4] only formed with an exact 1:1 stoichiometry, while an exce ...
The soln. structure of the two intimate ion pairs present in soln. for [PtMe(h2-olefin)(a-diimine)]BF4 compds. (1-3, shown as I.BF4, R = Ph, 4-MeC6H4, 4-CF3C6H4) their relative abundance and the consequent thermodn. equil. parameters were detd. by a quant. ...
Transient absorption spectra of C60 mols. trapped in cryogenic rare gas matrixes and dissolved in room temp. toluene were measured with a time resoln. of 90 fs. An absorption build-up with a characteristic rise time of 200 fs is measured, which is solvent- ...
