The density of the charge in slow surface states (∼ 10^12^cm^−2^V^−1^) is estimated from the ratio of the potential drops in the space charge region and the Helmholtz layer. These potential drops are determined from measurements of the surface conductance and electrode capacity of the germanium‐methylformamide system. The dependence of the instantaneus photovoltage on the potential, and also the measurements of the surface recombination velocity and electrode capacity, indicate presence of a considerable density of fast surface states (≥ 10^11^ cm^−2^) whose energy levels are well removed from the centre of the forbidden gap. The concentration of minority carriers at the boundary of the space charge region changes when the electrode is charged by short rectangular current pulses. An increase or decrease in this concentration causes a rise or fall, respectively, in the electrode capacity compared with that of the static case.
