Abstract
The different (structural and chemical) properties of oxide single-crystal surfaces that can be exploited for the growth of self-assembled oxide nanostructures are briefly reviewed. A large variety of nanostructures can be obtained, controlled by surface and interface structure and chemistry, which play a predominant role in their formation mechanisms at this nanometer scale. It is reminded that surface atomic order, surface steps, chemical terminations or heteroepitaxial strain can be used to generate various nanostructures such as nanodots, nanowires, nanostripes, with controlled size, morphology and spatial ordering.

Oxides present a wide range of remarkable properties that lead to various competing devices such as sensitive sensors, non-volatile memories, low consumption transistors, energy harvesters, and transducers, etc. [1]
Functional oxide nanostructures can even exhibit enhanced or novel physical properties compared to their bulk counterparts, and are of great interest for future devices in various application fields
