Research output: Contribution to journalArticlepeer-review


We have demonstrated theoretically and experimentally the strong dielectric enhancement of excitons in near-surface InGaAs/GaAs quantum wells, caused by the abrupt, one order of magnitude, decrease of the dielectric constant at the semiconductor-vacuum interface.
