Implication

Experimental analysis compares energy distributions and contact potentials in semiconductors and metals, suggesting novel insights into photoelectric behavior.

Key Points

This research aims to compare the photoelectric emission characteristics and contact potentials of semiconductors with metals.
Conducted experiments on Te, Ge, and B using spherical photo-tubes with interchangeable emitters.
Analyzed current-voltage characteristics to determine contact potentials.
Measured photoelectric yields and derived parameters from energy and spectral distributions.
Observed a pronounced sparsity of electrons near the Einstein maximum in semiconductors compared to metals.
Defined parameters, m values were typically 1.5 and 2, and delta values ranged from 0.10 to 0.5 ev for different semiconductors.
Photoelectric yields varied rapidly with energy, and stopping potentials were not clearly defined in the examined semiconductors.
