Photograph of an oxide chip containing several hundred thousand LaAlO3 - SrTiO3 field effect transistors. The colors are caused by light interfering with the transistor arrays (Carsten Woltmann).

Photograph of the laser ablation process in the PLD chamber.
The invisible, ultraviolet beam of an excimer laser hits a SrTiO3 target so that it shines as a blue disk (middle, top), creating a plasma plume (blue) which extends towards the substrate, a crystal of SrTiO3 (white rectangle in the middle, bottom).
A second invisible infrared laser beam heats the substrate to 1200°C, so that it glows white.
