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 ...
Intermetallic Ni3Al has been deposited by means of magnetron sputtering on substrates with an amorphous surface structure. The source was a homogeneous mixture of Ni-AI 75:25 % in the solid phase. The lateral and perpendicular grain sizes are below 20 nm. ...
A systematic study of the mass spectra of particles formed in a supersonic nozzle expansion of Zn, Cd, and Hg vapors together with Na was performed. The particles discussed in this paper contain only 1 heavy atom and
It is the purpose of this report to summarize the state of knowledge regarding the hydration of C//3A and C//4AF in the presence of calcium sulfate at ordinary temperatures. These interstitial phases in combination with calcium sulfate may comprise up to 2 ...
We have carried out high-resolution photoemission experiments on two quasi-one-dimensional compounds: K0.3MoO3 and (TaSe4)2I. In both systems, a metal-insulator transition associated with a lattice distortion is reported. We show that the Fermi-step charac ...
Structural, electronic, and vibrational properties of NanMg clusters (n = 6-9, 18) have been detd. using the Car-Parrinello method. We find that in the energetically preferred structures the magnesium impurity is never located at the center of the cluster. ...
We explore the formation of Schottky barriers by adsorption of Ge overlayers onto single crystal Ni and Ag substrates. The results are compared to earlier results from Si-on-metal systems as well as interfaces formed by the metal-on-semiconductor depositio ...
Although a-lithio ylide Ph3P+C-HBr was generated from [Ph3PCH2Br]Br through halogen-metal exchange, the reaction of Ph3P+C-H2 with Me3CLi or Me2CHCH2Li produces the o-lithio ylide I nearly quant. I is stable at -60 Deg but slowly decomps. at higher temps. ...
We present the resitivity and structural studies of the melt-spun Al-Mn alloys (with 10-18 at% Mn) that contain more than 50 vol% of the quasicrystalline (qX) Al//4Mn phase. The resistivity varies little with temperature up to approximately 600 K where it ...
