Quantum-confined Stark effect at 1.3 µm in Ge/SiGe quantum
... The absorption spectra obtained from this method is reported in figure (2). As a consequence of the confinement effect in the MQW and the strain between Ge in QW and the VS, a shift of absorption edge from 0.8eV for bulk Ge to 0.96eV is clearly observed. At low reverse bias (-1V is used in order to ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
