MDC C-V and I-V systems:

  • Dielectric constant and its temperature dependence for GaAs, CdTe, and ZnSe (direct link): The dielectric constants of GaAs, CdTe, and ZnSe and their temperature dependences were found from low‐frequency capacitance measurements.
  • Impurity peak formation during proton-enhanced diffusion of phosphorus and boron in silicon (direct link): In this study a sample temperature of 700°C, proton-beam energies of 50–140 keV, proton-beam current densities of ∼1 μA/cm2, and proton-bombardment times of 3 min to 3 h were used. The resultant impurity profiles were obtained using Schottky-barrier differential CV techniques.
  • Effect of radiation induced defects on the capacitance of silicon detectors, 1992 (direct link): The capacitance was measured at different frequencies and temperature. It was shown that the capacitance of the irradiated detectors strongly depends upon temperature.
  • Electrical properties of ion-implanted p-n junction diodes in β-SiC, 1988 (direct link): High-temperature implantation of Al(+) into n-type and of N(+) into p-type beta-SiC (100) thin films was performed, and the mesa structure junction diodes thus produced were characterized by measuring current-voltage (I-V) and capacitance voltage (C-V) as functions of temperature.
  • Stability of Sulfide Passivated Gallium Arsenide Surfaces, 1993 (direct link): Surface chemistry was characterized by Auger electron spectroscopy and barrier heights were calculated from C-V measurements obtained with a Hg probe.

  • Stable biopassive insulation synthesized by initiated chemical vapor deposition of poly (1, 3, 5-trivinyltrimethylcyclotrisiloxane), 2007 (direct link): In this work, the material properties and neural cell compatibility of a novel polymeric material, poly(trivinyltrimethylcyclotrisiloxane) (poly(V3D3)), are demonstrated to be suitable for application as permanently bioimplanted electrically insulating films.
