Shane Lindemann has been selected to give a colloquium in the North American Materials Colloquium Series (NAMCS)

Oct. 1, 2020

Shane is presenting on October 1st and 2nd at 3pm EST, along with another speaker. This inaugural program of the NAMCS will showcase some of the best and brightest senior graduate students and post-doctoral scholars in the field of materials science and engineering. This highly selective series is intended to provide visibility to future leaders in our field. Thirty-five universities in the United States and Canada are taking advantage of the series as part of their regular fall semester seminar series or are promoting talks within their campus materials communities.

Eom receives Vannevar Bush faculty fellowship to study antiperovskite materials

May 13, 2020

The Department of Defense has selected Chang-Beom Eom, a professor of materials science and engineering and physics at the University of Wisconsin-Madison, to receive a 2020 Vannevar Bush faculty fellowship. The five-year, single-investigator award includes $3 million in funding to support basic research with the potential for transformative impact.

Mike Patton earns NSF Graduate Research Fellowship Honorable Mention

Apr. 2, 2020

Oxide Lab group member Mike Patton earned an honorable mention in the 2020 NSF Graduate Research Fellowship program. Mike joined the group in 2018 as a graduate student and works on spintronics, particularly IrO2 thin films. Mike is the only student from the MS&E department to be selected for an honorable mention.

Crystal-stacking process can produce new materials for high-tech devices

Feb. 5, 2020

Collaborating with the Kim group at MIT, we demonstrate an alternative to heteroepitaxy growth to make complex-oxide materials. By creating free standing thin films using a new exfoliation technique, physical properties of thin films like piezoelectricity and magnetostriction can be freed from the constraints of a substrate. Further, free standing films can be combined to arrange artificial heterostructures unconstrained by different crystal structures and orientations. Read the full paper

Eom awarded $1.7M grant from Moore Materials Synthesis Investigator program

Jan. 22, 2020

Chang-Beom Eom has been selected for a $1.7 million award from the Moore Materials Synthesis Investigator program. The Emergent Phenomena in Quantum Systems (EPiQS) initiative aims to accelerate research in novel synthesis and new quantum materials.

Eom named as AAAS Fellow

Nov. 29, 2018

The American Association for the Advancement of Science has named Professor Chang-Beom Eom an AAAS Fellow for his contributions to the heteroepitaxy of complex oxide films, including the development of 90° off-axis sputtering, conducting oxides and strain-engineering to enable oxide electronics.

Switching identities: Revolutionary insulator-like material also conducts electricity

Nov. 29, 2018

In our new paper in the journal Science, we show that the metal-insulator transition in VO2 can be decoupled into an electronic and structural transition. By growing a layer of oxygen-deficient layer of VO2 ontop of VO2, we show that the combined sandwich can switch electrically without a structural transition, an important step toward ultrafast switching devices.

Beyond silicon: researchers solve a materials mystery key to next-generation electronic devices

Feb. 5, 2018

Evidence of a two-dimensional electron gases analog, a 2D hole gas, has been reported in our recent Nature Materials paper. Strontium titanate / Lanthanum aluminate / Strontium titanate structures were fabricated with high crystalline quality which allowed the 2D hole gas at the interface between the top strontium titanate layer and the lanthanum aluminate mid layer.

‘Magnetoelectric’ material shows promise as memory for electronics

Nov. 29, 2017

For the first time, we have used monodomain Bismuth ferrite films to create a magnetoelectric device using room-temperature exchange coupling to a Cobalt overlayer. Our report in Nature Communications show that switching the BFO film electrically changes the magnetic easy axis of the ferromagnetic Cobalt layer.

New material combines useful, typically incompatible properties

Apr. 20, 2016

Is it a metal or is it an insulator or is it both. We report in Nature the polar metal nature of LaNiO3. The material is electrically conducting but also have polarization, a property only found in insulators. Normally, free carrier found in metals elimates any polar ordering but the distortion of the Lanthanum aluminate substrate is preserved in the Lanthanum nickelate preserving it.
