Brillson receives Interdisciplinary Research Award

CEM Faculty member Len Brillson was awarded, in conjunction with Profs. Wu Lu and Stephen C. Lee, a Lumley Interdisciplinary Research Award. The three professors, members of the Departments of Electrical & Computer Engineering (Brillson, Lu) and Biomedical Engineering (Lee), have worked together to research the use of Field-effect Transistors (FETs) as protein sensors for biomedical applications. The development of this technology may lead to faster and cheaper diagnostics in clinical, biotechnological, and environmental applications.

The Lumley Interdisciplinary Research award was established in honor of John H. Lumley, a 1927 graduate of ceramic engineering, in 2002 to recognize interdisciplinary research accomplishments of College of Engineering faculty and research staff.

Congratulations Len!

Article on Ferrimagnetic Epitaxial Films published in APL

A team of CEM researchers including Profs. Fengyuan Yang, Pat Woodward, David McComb, Hamish Fraser, & Patricia Morris, as well as student and staff researchers Jeremy Lucy, Adam Hauser, Hailong Wang, Jenni Soliz, Manisha Dixit, and R. Williams have published an article in Applied Physics Letters titled, “Buffer-layer enhanced structural and electronic quality in ferrimagnetic Sr2CrReO6 epitaxial films.”

The article describes how the structural and electronic qualities in Sr2CrReO6 epitaxial films were enhanced through the minimization of defect states, particularly at the substrate – film interface. Minimization of the defect states was achieved through epitaxial growth of the Sr2CrReO6 double perovskite on an insulating and non-magnetic double perovskite buffer layer, Sr2CrNbO6. Crystalline quality and Cr/Re ordering in this material are crucial for intrinsic behavior such as semiconductivity at room temperature.

CEM team’s research in IEEE Spectrum article

The work of one of CEM’s teams of researchers has caught the attention of the writers at IEEE Spectrum. The team led by Profs. Josh Goldberger, Roland Kawakami, and Jay Gupta is working on creating 2-D structures of germanium and studying the new material’s capabilities for transporting electrons. In July 2013, IEEE Spectrum published an article reviewing the latest research on 2D materials titled, “The Flat Menagerie”, in which the 2-D research team’s work is mentioned. An abstract can be viewed here.

2014 OSU Business Plan Competition

The annual OSU Business Plan Competition is under way! This event, hosted by the Center for Entrepreneurship at Fisher College of Business, will kick-off with a Launch Day on Wednesday, October 2 from 6:00 – 8:00 PM.

Materials-related projects have participated and placed well in past competitions, with past winners even starting in successful spin-off companies!

CEM researchers develop new imaging tool for spin research

New imaging tool, “Scanned Spin-Precession Microscopy”

Scanned Spin-Precession Microscopy

A new technique for imaging spin properties at the nanoscale, Scanned Spin-Precession Microscopy, works by incorporating a scannable micromagnetic tip in conjunction with any of a variety of established spin detection tools—electrical or optical, and improves upon their limited or non-existent imaging capabilities. The magnetic field gradient from the probe directly selects spins from certain regions of the sample for study. The technique can achieve high resolution, beyond the optical diffraction limit, governed by the field gradient strength in a manner analogous to MRI.

This new tool should help in further understanding the microscopic details relevant to spin and its transport and will be an asset to researchers in spintronics, especially in the study of technologically important materials such as silicon and graphene that have been challenging to investigate with current tools. The new technique, pioneered by a collaborative team of experimentalists and theorists from OSU and Texas A&M, is to be highlighted as an Editor’s Suggestion in Physical Review Letters.

The article can be read here and will be published in Physical Review Letters on 13 September 2013.
