Chemical bonding states at silicon / silicon dioxide interfaces characterisable with light

The study identifies special bonding states at silicon / silicon dioxide interfaces, which can be observed due to the structure of a (111)-terminated silicon crystal. Nonlinear-optical spectroscopy provides high interfacial sensitivity, allowing for detailed analysis of oxidation processes.

The end of the line for silicon dioxide?

Researchers at TU Vienna and Clausthal have discovered a new material, strontium titanate, that can be used as a gate oxide to overcome the miniaturization limit of transistors. The material's electrical properties can be controlled by chemical processes at the interface, enabling the design of even smaller and more efficient transistors.
