- W2004177870 abstract "The brightness of negative-electron-affinity photocathodes was measured to determine their applicability as an electron beam source for high-resolution, low-voltage scanning electron microscopes. The smallest electron source size was 3 µm, and the largest angular current density was 41 mA/sr at an extraction voltage of 2 kV. The resulting reduced brightness of 5.9×106 A·sr-1·cm-2·V-1 was about one order of magnitude higher than that of an LaB6 emitter and about one order lower than that of a Zr-O/W Schottky emitter. The limited brightness was due to the space charge effect at the GaAs surface. The brightness was improved using a GaAs film with a thinner depletion layer and using a pulsed excitation beam to prevent charge accumulation on the surface. The use of these techniques will enable the use of an NEA electron gun in small electron probes, which is expected to be a powerful tool for low-voltage scanning electron microscopy." @default.
