Radio-frequency impedance measurements using a tunnel-diode oscillator (TDO) technique

, 1999
A resonant method based on a tunnel-diode oscillator (TDO) for precision measurements of relative impedance changes in materials, is described. The system consists of an effective self-resonant LC-tank circuit driven by a forward-biased tunnel diode ...

Electrode polarization at the Au, O2(g)/Fe implanted yttria-stabilized zirconia interface [PDF]

, 1992
Ion implantation has been applied to modify the surface properties of yttria-stabilized zirconia (YSZ). A three-electrode cell was used for measuring steady state current-overpotential curves and for determining the electrode impedance.
