Some results of a study of the noise of silicon field emitters are presented. The basic experiments were performed on p-type crystals with a resistivity of 2000 ohm. cm in a vacuum of 10** minus **9 torr. The I-V characteristics of these field emitters are highly nonlinear and have a characteristic light-sensitive saturation region. Considering the low noise level of electron field emission, a noise meter was built employing a zero modulation radiometer scheme.
