Doping Bi2Sr2Ca1Cu2O8+y with Co causes a superconductor-insulator transition. We study correlations between changes in the electrical resistivity rho(ab)(T) and the electronic bandstructure using identical single crystalline samples. For undoped samples th ...
The use of TLDs for the determination of gamma-heating effects in various materials, spanning a Z-number range of ~4-82, has been assessed in the light of temperature measurements across specially designed experimental assemblies. A large planar 60Co sourc ...
Electron cyclotron resonance heating (ECRH) experiments at 39 GHz with power levels similar to those of Ohmic heating have been conducted in the TCA tokamak, in either the X-mode or the O-mode. ECRH was observed to be more efficiently absorbed in low densi ...
The coating of PbO2 [1309-60-0] on Ti was carried out after activation of the Ti in boiling HCl 20% and after predeposition with an intermediate protective Au layer. The stability measurements of this electrode showed that the rate of decompn. of PbO2 in H ...
Pyrolytic and photolytic laser chem. vapor deposition of Cu, Pt, Ga, and Sn was studied for the prodn. of low-resistance ohmic contacts of very small dimensions. ...
We studied the influence of the indium composition y, growth temperature T(s) and InGaAs quantum-well channel thickness d(ch) on the 300 and 77 K Hall electrical properties of pseudomorphic modulation doped field effect transistor (MODFET)-type heterostruc ...
Microscopic ohmic contacts are made by laser chem. vapor deposition of platinum on a Pyrex substrate. The elec. cond. of the deposited metal stripes is measured as a function of the laser power, the writing speed, and the organometallic vapor pressure. The ...
