Professor Collins’s research involves the development and application of polarized light spectroscopies based on ellipsometry and polarimetry to probe the optical properties of solids, surfaces, and thin films. Instrumentation development in Prof. Collins’s laboratory focuses on multichannel spectroscopic and imaging techniques that can be performed in real time during the fabrication and processing of materials. The material systems of interest include those used for thin film photovoltaics (such as amorphous and nano/microcrystalline silicon, transparent conductors, and polycrystalline CdTe) and those used for protective coatings (such as diamond, BN, and TiN). The goals of the research range from achieving a basic understanding of thin film growth and optical properties to improving industrial processes for photovoltaic thin films and other coatings.
