Welcome to the Collins Group at Washington State University. Our research is highly interdisciplinary, straddling physics, materials science, electrical engineering and chemistry. We specialize in developing and using synchrotron X-ray techniques to investigate carbon-based materials designed to have novel optoelectronic properties. We strive to understand how interactions of organic molecules and polymers in aggregate and at interfaces govern the creation, transport, and annihilation of excited and charged states that result in power generation/storage, illumination, sensing and information processing.
Terry McAfee joins as Postdoctoral Researcher
Terry McAfee has joined the Collins Research Group as postdoctoral researcher. He obtained his PhD in physics from North Carolina State University under Professor Harald Ade. His thesis was titled “Characterization and control of morphology in organic photovoltaic devices.” Recently, he completed postdoctoral work at Tulane University under Professor Wayne Reed developing an Automatic Continuous Online Monitoring of Polymerization (ACOMP) system. Terry joins the Collins group to develop a new Environmental Resonant Soft X-ray Scattering instrument which will enable in-situ/in-operando structural measurement of organic materials.Read Story

Measurement of buried molecular interfaces enabled by resonant X-ray scattering analysis
We demonstrate a new quantitative X-ray scattering analysis that probes 3D molecular nanostructures and even buried interfaces between those structures. These organic nanomaterials are of increasing impact in bottom-up assembly, electronic devices, and biomimetic applications, but their internal structure is difficult to probe due to light elements and no or low crystallinity. For example, only planar interfaces were previously accessible with laborious and disruptive chemical tagging. This new … » More …Read Story
