Advanced Atomic Design Lab
The Alex Demkov Group

Welcome to the Demkov Materials Physics Group!

Our current research is focused on the physics of oxide heterostructres. We work on the quantum theory of real materials, and molecular beam epitaxy (MBE). We do both theoretical and experimental research. Owing to the complexity of these problems, our research requires high performance computing, most of which is done at the Texas Advanced Computing Center (TACC), and the state of the art MBE Lab . Below and to the right is a list of our most recent papers (a full list is available under the publications tab).

We are always interested in recruiting new students who are interested in condensed matter physics, and hope you will consider our group for your studies.

New Patent Issued
Prof. Demkov and Dr. Posadas have received a patent for their recent invention related to materials integration for spintronic devices - "Efficiently injecting spin-polarized current into semiconductors by interfacing crystalline ferromagnetic oxides directly on the semiconudctor material" (US Patent No. 9,023,66 issued 05/05/2015).

Exciting New Research Opportunity!
The group is excited to announce a new research opportunity to work with IBM Zürich on non-linear optics. Both experimental and theoretical opportunities are available. For more details, please visit the IRES Program page or e-mail Prof. Demkov.

Kurt Fredrickson Wins Ovshinsky Student Travel Award for Materials Physics
Kurt was one of the students selected by the APS Division of Materials Physics to receive one of this years Ovshinsky Travel Awards in order to attend the 2015 March meeting and present his current research on the ``Switchable two-dimensional electron gas at the interface of a ferroelectric and nonpolar insulator: BaTiO3/SrTiO3.''

Research Highlighted
The recently published research on the integration of BaTiO3, its switchable polarization, and charge modulation of Ge was recently featured in an article for the EE Times (the article can be found here, while the research article can be found here).

Patrick Ponath Wins Young Scientist Award
At the recent Physics & Chemistry of Surfaces & Interfaces conference (PCSI 42), Patrick Ponath won the Young Scientist Award for his recent work on the integration of ferroelectric BaTiO3 on Germanium. Read more.

Research Highlighted
The recently published research by the group (in collaboration with researchers at IBM T. J. Watson Research Center and Oak Ridge National Laboratory) on ``Switching of ferroelectric polarization in epitaxial BaTiO3 films on silicon without a conducting bottom electrode'' (Nat. Nanotechnol. 8, 748 (2013) has recently been featured on as one of the Top-10 Brookhaven Lab Breakthroughs of 2013. Their review of the work can be read here.

New Book on Functional Oxides
Professor Alex Demkov and Senior Scientist Agham B. Posadas are pleased to announce that they have written a book related to the research done by the group titled ``Integration of Functional Oxides with Semiconductors'' to be released in the Spring of 2014. The scope of the book is to provide an understanding of the physical principles of oxide/semiconductor epitaxy. The book describes the current state of the field both in theoretical and experimental advances. The book will be published by Spring under their Briefs in Materials series and can be purchased via Amazon.
