A casual opportunity immediately following the Millennium Café to learn about the breadth of analytical capabilities within the Materials Characterization Laboratory (MCL). These brief (30 minute) multi-technique and interdisciplinary talks will highlight applications (not theory) to provide useful insights to novice and experienced researchers working across various science and engineering challenges.
Spectroscopic Methods for Electronic Property Characterization at the MCL
This will be an opportunity to learn about a variety of new capabilities, new expertise, and recommended best practices to maximize your usage of the MCL. Whether you’ve been using MCL for years, are looking to start using the lab soon, or are just curious about MCL resources this event is for you. All students, faculty, and staff are invited to attend. Excellent coffee will be provided.
MCL now offers a range of analytical techniques that can be used to determine important electronic properties of your device or material system. These properties include: band gap (Eg), work function (WF), valence band maximum (VBM), ionization energy (IE), electron affinity (EA), conduction band minimum (CBM) and carrier concentration. We have techniques for studying electronic defect states in the band gap which can impact device performance and for those making heterojunctions we can determine valence and conduction band offsets. This talk will provide an overview of these parameters and how they can be measured within MCL along with details about sample requirements and limitations. - Jeff Shallenberger
