Dr. Comes will be sharing some of his postdoctoral work at the International Workshop on Oxide Electronics on Wed, Sep 27 in Chicago. He’ll be sharing work on the LaFeO3/n-SrTiO3 interface that was published last year in Physical Review Letters and recently submitted work led by Dr. Steven Spurgeon using electron microscopy and density functional theory modeling…Continue Reading Dr. Comes Presenting Talks at International Workshop on Oxide Electronics and University of Alabama
Paper on MBE-grown Oxide Nanocomposites Published in Advanced Materials Interfaces
Dr. Comes’ paper in collaboration with Steven Spurgeon and Daniel Perea at Pacific Northwest National Laboratory has been published in Advanced Materials Interfaces. In this paper we demonstrate the first growth of an epitaxial oxide nanocomposite by molecular beam epitaxy (MBE). Almost all of the previous work had focused on depositing materials by pulsed laser deposition,…Continue Reading Paper on MBE-grown Oxide Nanocomposites Published in Advanced Materials Interfaces

Study on Interfacial Properties of SrTiO3/Ge Heterostructures Published in Applied Physics Letters
Our collaborative paper led by Dr. Scott Chambers at Pacific Northwest National Laboratory studying the electronic band alignment and interfacial behavior at the epitaxial SrTiO3/p-Ge interface has been published in Applied Physics Letters. Using molecular beam epitaxy of SrTiO3 was grown on a p-doped Ge substrate and characterized using x-ray photoelectron spectroscopy (XPS) and scanning transmission…Continue Reading Study on Interfacial Properties of SrTiO3/Ge Heterostructures Published in Applied Physics Letters
Paper on Oxide-Water Surface Chemistry Published in Journal of Physical Chemistry Letters
Our paper exploring the surface reactivity of LaFeO3 thin films with water using ambient pressure x-ray photoelectron spectroscopy (AP-XPS) has been published in Journal of Physical Chemistry Letters! This work was led by Kelsey Stoerzinger at Pacific Northwest National Lab, who performed AP-XPS measurements on LaFeO3 epitaxial thin films with FeO2 and LaO surface terminations at the…Continue Reading Paper on Oxide-Water Surface Chemistry Published in Journal of Physical Chemistry Letters
Paper on SrTiO3-LaCrO3 Superlattices Published in Chemistry of Materials
Our work exploring the role of interfacial defects on polarization and conductivity in SrTiO3-LaCrO3 superlattices has been published in Chemistry of Materials. In this work, we explore the effects of off-stoichiometry defects and oxygen vacancies on interfacial carriers and polarization in these superlattices. The work was a collaboration during Dr. Comes’ post-doctoral work at Pacific Northwest…Continue Reading Paper on SrTiO3-LaCrO3 Superlattices Published in Chemistry of Materials

Portions of this work have been published in Physical Review Letters, Chemistry of Materials, and Advanced Materials Interfaces in…Continue Reading Invited Talk at Electronic Materials and Application 2017
Work on LaFeO3/n-SrTiO3 Interface Published in Physical Review Letters
Dr. Comes’ work on the LaFeO3/n-SrTiO3 interface has been published in Physical Review Letters here! In this work, which was done at Pacific Northwest National Laboratory in collaboration with Dr. Scott Chambers, we show that the band alignment between LaFeO3 (LFO) and Nb-doped SrTiO3 (STO) is relatively insensitive to the interfacial termination. We synthesized a…Continue Reading Work on LaFeO3/n-SrTiO3 Interface Published in Physical Review Letters
