The conduction current to a probe incorporated into an electrode is proportional to the strength of the charge-carrier drift field; this current is modulated by a bias voltage applied betwen the probe and the electrode. The current/bias-voltage probe characteristics are described which have been derived from computation of the bias field distribution. From(More)
The principles of the field-filter probe, which is capable of measuring both field changes and conduction current at an electrode in the presence of space charge, are described. Design characteristics are given for a simple field filter and for two further types which can be used for bipolar (reversing) fields and currents. Measurements are given for the(More)
