Electrons: collective or independent – that sometimes lies in the eye of the beholder
- Research
- Ultrafast science
- Physics
- Institute for Quantum Electronics (IQE)
Absorption of light adds energy to a material. The electrons inside the material can react collectively or independently to that energy. Here, the dominant reaction pattern should not depend on perspective. However, in compound semiconductors, surprisingly, divergent responses are obtained depending on which atomic constituent is consulted. Knowledge of both perspectives is necessary to optimize new materials for applications in electronics and optoelectronics.
