A stable LaB<inf>6</inf> nanoneedle field-emission electron source for atomic resolution imaging with a transmission electron microscope
2022, Materials TodayCitation Excerpt :A curve fitting was carried out on Sn with respect to frequency (f) up to 0.1 Hz because the shot noise started to dominate the noise and it became independent of f in the range of frequencies greater than 0.1 Hz. Sn shows a dependence on f with the power of −0.42, which is greater than the usual value of −1 obtained for field-emission noise from W(310) emitter or carbon nanotubes and it is also slightly greater than the value of −0.53 of our previous results on the noise of LaB6 nanowire [23,38,39]. These data demonstrate further that the LaB6 nanoneedle has an excellent stability in emission current and the thermal flashing is only required no more than once every week.
