Randomized trial reveals photoelectric yields in metals, indicating contamination impact on thresholds.

Key Points

The study aims to compare photoelectric currents from fresh metal films with those exposed to air, focusing on the volume photoelectric effect thresholds.
Compared photocurrents from fresh metal films with air-exposed films.
Evaporated films at low pressures (10−8 to 10−7 torr) on top of pre-existing films.
Quantified photoelectric yields for aluminum, bismuth, and indium using established data.
The photoelectric yield per incident photon exhibited a steep slope in air-exposed films but diminished for fresh films.
Quantum yield for aluminum remained constant within 15% across the measured range.
Findings suggest previously identified volume photoelectric thresholds are attributed to gaseous contamination.
