Development of next generation electrochemical devices such as solid oxide cells requires control of the charge transferprocesses across key interfaces. Structural strain at electrolyte:electrode interfaces could potentially alter the devicescharge transport properties, therefore understanding the structural behaviour of electrode surfaces at operating conditionsis important. The functional oxide single crystal substrate SrLaAlO4 has been well-characterised with bulkstructure studies, however there are very few studies of SrLaAlO4 surface structures. Here we present an investigationof the surface structure of SrLaAlO4(001) substrates using surface X-ray diffraction, under UHV conditions (1010torr) with the substrate held at either room temperature or 650 C. Best-fit models using a 1:1 ratio of Sr:La showedsignificant distortions to the surface AlO6 octahedra.
