- UC Santa Cruz - B.S. in Physics
From Ventura, California, Ryan DeCrescent received his B.S. in Physics at the University of California in Santa Cruz in 2014. He is currently a Ph.D. student in the Physics department at UC Santa Barbara.
We study the optical response of small-molecule and polymer thin films in order to understand the connection between molecular orientation and optical anisotropies. With this, we hope to gain insight into, e.g., possible ways of increasing absorption/emission properties of organic photovoltaics/LEDs. We work closely with groups in the chemistry and materials department in attempts at understanding novel "advanced energy" materials. Our primary apparatus is a custom-built momentum-resolved (aka, Fourier imaging) spectrometer, constructed by Steven J. Brown. This setup is capable of both reflectance (i.e., "momentum-resolved reflectometry") and luminescence (e.g., "momentum-resolved photoluminescence") intensity measurements. This allows us to measure emitting and absorbing dipoles aligned parallel and perpendicular to the substrate, independently. We're continuously exploring new capabilities of the setup, including, e.g., angle-resolved Raman scattering.
