摘要：

An effective method for mass production of field-emission microcathodes (mu FECs) is suggested and described. The main properties of the mu FECs are calculated using the actual geometric parameters of the system (emitting nanotip radius similar to 15-20 nm, interelectrode distance similar to 1.5-2 mu m, etc.). It is shown that the electric field strength in the immediate vicinity of a nanotip is several units of 10(7) V/cm at comparatively low (100-200 V) voltages applied. A series of probable applications taking advantage of the unique features of the mu FECs are suggested. (C) 2010 Elsevier B.V. All rights reserved.
