Bending a selenium rectifier disk causes a temporary increase of the current flowing through it in both directions. The effect (discovered in December 1942) is especially pronounced in the reverse ...

It is shown how the image force can be taken into account very simply by making a minor improvement in the current theory of rectification. The equations obtained have been compared with experimental ...

FATIGUE in selenium rectifier photocells is generally marked by a falling off in the current output, during exposure to steady radiation, of cells which have been kept for some time in darkness. The ...
