Effects of low energy hydrogen ion shower (LEHIS) treatment on the optical and thickness properties of polytetrafluoroethylene (PTFE) materials
Abstract
The optical and thickness properties of polytetrafluoroethylene (PTFE) materials treated by low energy hydrogen ion shower (LEHIS) of a Gas Discharge Ion Source (GDIS) are explained using scanning electron microscopy (SEM) and ellipsometry characterizations. Results show that as the discharge current is decreased, the PTFE materials thickens as indicated by the increase in the index of refraction, density, and from its SEM cross sectional view. The thickening of the material reduces the transmittance of light to the sample to as low as 60%.
