Abstract: Spectral analysis of the field emission (FE) current fluctuations has been carried out at the base pressure ~1�10-8mbar. The emission current stability investigated at preset value of 2?A is characterized by 'step' like fluctuation. The spectral analysis performed on a FFT (Fast Fourier Transform) analyzer revealed that the observed noise is of 1/f? type, with the value of ? as ~1.05. The estimated value of ? implies that the current fluctuations are mainly due the various processes occurring on atomic scale like adsorption, migration, and/or desorption of the residual gas species on the emitter surface. � 2014 Elsevier B.V.
