  • Website launch: ONR-MURI on Phase-Change Photonics

    The website for the new ONR-MURI on phase-change materials for photonics is now live!

  • Fililppone et al. (2018) – our group’s first paper!

    Congrats to Stephen for publishing our group’s first paper, a thermodynamic study of complex chalcognide growth, published today in MRS Communications! 

  • Deposition rate tool now online

    We recently a posted a set of deposition rate tools that we find useful for physical vapor deposition. We hope they’re useful for a broader audience. Please let us know…

  • Tutorial on chalcogenide electronic materials – slides avilable!

    Together with Stephan Lany and Prashun Goai from the National Renewable Research Laboratory, I presented a tutorial associated with the Chalcogenide Semiconductor Research and Applications (CSRA) symposium at the 2017…

  • New symposium at EAM 2018 (Orlando)

    I’m pleased to announce symposium “S1. Complex oxide and chalcogenide semiconductors: Research and applications” that will be held at the American Ceramics Society Conference on Electronic and Advanced Materials (EAM)…

  • New symposium at IMRC 2017 (Cancun)

    I’m pleased to announce a new symposium called “Chalcogenide Semiconductor Research and Applications” that will debut at the International Materials Research Congress (IMRC), August 2017, in Cancun (Mexico). Abstracts are…

  • New paper shows how atomic segregation affects Schottky barrier transport

    Controlling oxide-silicon semiconductor heterojunctions is a perpetual challenge in engineering electronic devices, including field-effect transistors and solar cells. We used advanced microscopy to perform an atom-by-atom deconstruction of the interface…

  • New paper highlights importance of minority carrier lifetime for solar cells

    New paper published today in the Journal of Applied Physics describes transient THz photoconductivity measurements of minority carrier lifetime in SnS thin films. Figure 1 (copied here) presents a survey…

  • New, freely-available software for characterizing solar cell materials

    We just released a new software suite for determining minority carrier recombination rates in semiconductor thin films using transient photoconductivity data. The software was written to better understand optical-pump, THz-probe…
