Learn more about spectroscopic ellipsometry by viewing educational videos and discover some of the applications with our collection of webinars.
Spectroscopic ellipsometry allows a range of thin film properties to be characterized, like layer thickness, optical properties (n,k), optical band gap, interface and roughness thickness, film composition, uniformity by depth and area, and more.
Materials suitable for spectroscopic ellipsometry include semiconductors, dielectrics, polymers, organics, and metals. Ellipsometry can also be used to study solid-liquid or liquid-liquid interfaces.
HORIBA spectroscopic ellipsometers use innovative technology to perform high frequency polarization modulation measurements without any mechanical movement, thus giving a faster, wider range and higher precision of characterization when compared to conventional ellipsometers.
With their ~20 % efficiency, hybrid perovskite solar cells are the new promising candidate for next generation photovoltaics. Thanks to the wide HORIBA Scientific portfolio, different techniques can be used to gain in depth knowledge on the optoelectronic properties and mechanisms of this class of materials. In this application note we decided to use spectroscopic ellipsometry, steady-state and time-resolved fluorescence and Glow Discharge Optical Emission Spectroscopy to investigate the properties of CH3NH3PbI3 thin films deposited on a spin-coated PEDOT:PSS. The impact of the exposure to air was addressed.Read more
