TL;DR: In this paper, a new ac bridge technique was proposed for detailed photoelectric studies on very small particles suspended in gases, and the photoelectric yield was shown to follow the Fowler-Nordheim law.
Abstract: A new ac bridge technique allows detailed photoelectric studies on very small particles suspended in gases. The photoelectric yield $Y$ near threshold $\ensuremath{\Phi}$ still follows the Fowler-Nordheim law $Y=c{(h\ensuremath{
u}\ensuremath{-}\ensuremath{\Phi})}^{2}$; yet $c$ is generally much larger compared to surfaces of extended solids. For Ag particles of radius 20 \AA{} in an airlike mixture of ${\mathrm{N}}_{2}$ and ${\mathrm{O}}_{2}$, $c\ensuremath{\simeq}100{c}_{0}$, where ${c}_{0}$ applies to a macroscopic Ag surface in the same environment.
