The objective
The prime objectives of this programme are to explore novel quantum transport features of (nano) structured 2-dimensional electron gasses (2-DEGs) based on combinations of complex oxides, and the tailoring of these oxide 2-DEGs for potential applications.

Background, relevance and implementation
In recent years, great progress has been achieved in the creation and basic exploration of unconventional 2-dimensional electron gases ('2-DEGs') arising at complex oxide interfaces, such as LaAlO3 and SrTiO3. In this endeavor, Dutch groups have played an important role, facilitated for an important part through the FOM 'InterPhase' programme (2009-2013). Building on the knowledge and expertise obtained, this research field is now facing new scientific challenges, both of a fundamental as well as technological nature.

The prime goal of the programme is to address the most essential challenges, relating in particular to novel quantum transport features and to the tailoring of complex oxide 2-DEGs for potential applications. In this, it will have a focus on advanced nano-device structures, involving also novel materials combinations. 

The research in this programme is of great relevance for the emerging field of oxide electro­nics, in which the outstanding, multifunctional properties of complex oxides are employed for future electronics as well as sensing applications. Particularly attractive prospects of oxide electronics are the potential to realize controllable device-structures well below the 10nm scale, in a regime where standard semiconductors can no longer be regarded as being electronically homogeneous, and the realization of low-power switching devices and novel basic electronic elements such as memristors for neuromorphic circuitry.

The research will be implemented in a close collaboration between research groups at five Dutch universities and with an additional close link to the LCLS-facilities at Stanford University. To reach the main goals of the programme, 43 project milestones have been defined, of which most will be pursued in collaborative effort of researchers from different universities involved in the programme.

The final evaluation will be based on the self-evaluation report initiated by the programme leader and is foreseen for 2019.
