Bloch transport of electrons and holes in superlattice minibands: Direct measurement by subpicosecond luminescence spectroscopy
Abstract
The perpendicular transport of photoexcited electrons and holes in graded-gap GaAs-AlGaAs superlattices is directly determined by subpicosecond luminescence spectroscopy. We show that the electron and and hole transport is through extended, Bloch-type states for superlattice periods 40 A\r{}, and determine the mobility for such transport. Increasing the superlattice period to 60 A\r{} reduces the mobility by a factor of 20, resulting from an order of magnitude reduction in the hole miniband width. Our results also provide the first evidence of diffusion enhanced by potential steps.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
