Abstract
THE magnitude of the fluctuations of current i in a diode valve known as 'shot-effect'obeys the well-known formula due to Schottky1 where I is the mean current, '?f is the integrated band-width of the measuring instrument, and e the electronic charge. The factor T2 is theoretically equal to unity under 'saturated conditions', that is, when the potential increases monotonically towards the cold electrode, and under 'retarding field conditions' when it falls monotonically towards that electrode ; under usual working conditions, however, the potential has a minimum somewhere between the electrodes and T2 < 1.
