Electronic reconstruction at oxide interfaces

In collaboration with Twente colleagues from the ICE, IMS, CMS and NE groups, the remarkable properties are being investigated of the interface between polar and non-polar oxides. The electronic reconstruction at these interfaces between insulating oxides gives rise to conductivity, large magnetoresistance and even electron-hole bilayers can be created with electron-hole separation distances as close as 1 nm.

In the FOM funded national program INTERPHASE, a Dutch consortium is formed to study novel electronic phases at oxide reconstruced interfaces.
