Figures

Image of FIG. 1.
FIG. 1.

SEM images of two field emitters. [(a) and (b)] show sample A, nonsharpened emitter with apex curvature, and [(c) and (d)] show sample B, sharpened emitter with (1–5) nm apex curvature, respectively.

Image of FIG. 2.
FIG. 2.

(a) Schematics of the photoemission electron microscopy and spectroscopy of field emitters excited by pulsed laser. (b) PEEM image of sample A when 4.5 nJ laser pulses irradiate the structure from the bottom left to the top-right direction. (c) Normalized spatially resolved photoelectron energy distribution. The inset shows the same spectra in log scale. The spectra were overlaid for clarity.

Image of FIG. 3.
FIG. 3.

(a) PEEM image of sample B having the emitter apex curvature in the order of (1–5) nm. (b) Normalized spatially resolved photoelectron energy spectra when the emitters were excited by 3 nJ pulses. The spectra were shifted vertically for clarity.
