| Abstract: | If the voltage applied to the system increases
from a low initial value to a maximum and then reduces progressively to the
initial minimum, the variation in rising and falling fields presents three
regions of I-V characteristic (i)
rising positive approximately linear characteristic up to the breakdown
potential of hydrogen gas (Vg),
(ii) sharply inverting to a negative characteristic over the region Vg-VV and (iii) a rising characteristic
once again for the potential above valley voltage (VV). The region of interest has been the potential range
Vg-VV for which the characteristic is
negative. The segments (ii) and (iii) form roughly a parabola. Results show
that for increasing and decreasing progress of the applied V, the values of unidirectional current are not identical. The
values are comparatively less in the increasing progress of the voltage than
those in the portion of the positive hysteresis (anti-hysteresis) corresponding
to decreasing voltage. These results are discussed and a mechanism for the
anti-hysteresis is proposed. |
