A simple metal can be described as a gas of non-interacting electrons. However, when electron correlations become strong many interesting and potentially useful phenomena occur. 

Designing oxide interfaces with a single unit cell resolution: Our laboratory is capable of making such heterostructures, for example, the BaO layer inserted between the SrTiO3 substrate and the polar LaAlO3 film forces growth with inverted LaAlO3 polarity. 

In our laboratory we tune through the electronic phase diagram of such systems using control parameters such as: chemical doping, pressure, electric and magnetic fields.  

Our goal is to discover new physics in correlated systems and to understand them. This will lead us to new or improved functionalities such as high temperature superconductivity, controllable ferroelectricity and ferromagnetism and tunable topological orders.  

We have the capabilities of making high quality samples and devices as well as performing unique measurements.  

Growing structures from oxides with a nanometer resolution as demonstrated in these images.  Here we demonstrate our capability to produce a quantum dot: A conducting island smaller than the Fermi wevelength with quantized states (An artificial atom)
