Ab initio study of interface states at metal contacts to III-IV semiconductors

We present a theoretical study of the physical characteristics of metal/semiconductor junctions. Using first principle pseudopotential calculations, we have investigated the nature of electronic states with energies within the semiconductor band gap of rep ...

A thallium coated dianion: trigonal bipyramidal [F2Al(OR)3]2- coordinated to three Tl+ cations in the ion pair [Tl3F2Al(OR)3]+[Al(OR)4]- [R = CH(CF3)2]

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 ...

Orientation of Rapid Thermally Annealed Lead-Zirconate-Titanate Thin-Films on (111) Pt Substrates

Nava Setter

The nucleation, growth, and orientation of lead zirconate titanate thin films prepared from organometallic precursor solutions by spin coating on (111) oriented platinum substrates and crystallized by rapid thermal annealing was investigated. The effects o ...

Valence Electronic-Structure of Thallium-Compound High-Temperature Superconductors

Giorgio Margaritondo

We used photoemission spectroscopy with synchrotron radiation to investigate the electronic structure of eight different thallium cuprates: pure Tl2.2Ba2CuO(y), Ce-doped Tl2.2Ba(2-x)Ce(x)CuO(y) (x = 0.1, 0.15, 0.2) and Tl2Ba2CeCu3O(y), and Zr-doped Tl2Ba(2 ...

Selective copper film growth on platinum clusters

Hubert van den Bergh

Two-step spatially delineated growth of copper lines from a solid copper formate layer on a surface is demonstrated. In the first step, a localized platinum film, less than 10 .ANG. high, is deposited. Subsequently the whole surface is covered by a few mic ...
