Production of an irreversible joshi effect in the hysteresis-range below the threshold potential
(1950) B.R. Marathe; S.S. Bommannavar
THE fundamental importance of the threshold potential Vm in the production of the Joshi effect Δi and the preferential incidence of the latter in the high-frequency components of the discharge current have been established1-6. Results were suggestive when Δi was studied in chlorine at and below Vm. Until this latter is reached, the current is small, say, i1; it increases suddenly by a large amount at V m, and rises rapidly thereafter. On decreasing the voltage below Vm, it decreased gradually to i1 at V1 (see graph). CA denotes iD, the current in the dark when the voltage is reduced below Vm, and DE the corresponding current iL under irradiation. The larger current (in the dark) while decreasing below the voltage Vm is due to hysteresis. © 1950 Nature Publishing Group.
