Terahertz conductivity of magnetoexcitons and electrons in semiconductor nanostructures

Terahertz conductivity of magnetoexcitons and electrons in semiconductor nanostructures

Using terahertz time-domain spectroscopy we investigate how quantum, magnetic and electrostatic confinement alters the photoconductivity of nanostructured semiconductors. In 2.0 THz and 2.9THz GaAs/AlGaAs quantum cascade structures under a magnetic field we observe transitions from the 1s to 2p- or...
