  • This effect is called the quantum-confined Stark effect (QCSE). 2 Besides this dc Stark effect, the ac or optical Stark effect in semiconductors has gained increasing in-terest recently. In ac Stark experiments, one has an ad-ditional degree of freedom as compared with the dc case. Besides the intensity which is connected to the electric-field strength, one can also tune the photon energy of
  • In this paper, we present observations of quantum confinement and quantum-confined Stark effect electroabsorption in Ge quantum wells with SiGe barriers grown on Si substrates.
  • the quantum con ned Stark e ect leads to the quantum con ned Franz-Keldysh e ect between the discrete levels of the well and passes over to the bulk Franz-Keldysh e ect in the limit of further increased well width [2].
