Professor Ade received his PhD in 1990 in Physics from SUNY at Stony Brook (now Stony Brook University) and joined the NCSU faculty in 1992. He has held appointments at NCSU ever since: Assistant Professor (1992-97), Associate Professor (1997-2001), and Full Professor (since 2001-2011), Distinguished Professor of Physics (2012-2017), and Goodnight Innovation Distinguished Professor (2017 – present).


Research Description

Prof. Ade developed a number of novel instruments and characterization methods, which include Near Edge X-ray Absorption Fine Structure (NEXAFS) microscopy, X-ray linear dichroism microscopy, X-ray photoemission microscopy, resonant x-ray reflectivity and resonant soft x-ray scattering (R-SoXS). Their applications focus primarily on determining the composition, morphology and structure of polymeric and organic electronic materials at the sub-micron spatial scale. R-SoXS has become a method de rigueur for the characterization of organic photovoltaic devices, as it affords high scattering contrast, sensitivity to molecular orientation, and a q-range that matches important lengths-scale of the device morphology. Instrumentation advanced in x-ray microscopy have lead to a commercial instrument by Accel (now Bruker). Click here to view a larger list of publications.
