FIG. 1.

(a) Schematic band structure of the heterostructure diode. The interband transitions used for photogeneration and detection of the transient hole ensemble are sketched by the vertical arrows. The lower part of the diagram depicts the band gap energy within the heterostructure. (b) Spectrally resolved transmission changes for various delay times after optical injection of electron-hole pairs for an electric field of obtained at room temperature.

FIG. 2.

Normalized transmission changes after photoexcitation observed for various electric fields (a) at and (b) at room temperature. Note the different scale of the abscissa. The dashed line in the lower diagram represents a typical theoretical simulation of the transmission change used to extract the drift velocity and the temporal broadening of the hole ensemble.

Image of FIG. 3.
FIG. 3.

(a) Mean hole velocity for the propagation through the heterostructure extracted from the transient transmission changes. (b) Temporal broadening of the hole ensemble after a propagation of 240 nm through the heterostructure. Circles: , triangles: . The solid lines are a guide to the eye.
