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.
