ABSTRACT
The Hall coefficient of p-PbTe doping superlattices changes sign twice between 100 and 300 K. This effect is reported here for the first time and explained in terms of the temperature dependences of the static dielectric constant and the electron and hole mobilities. Below 140 K, persistent photoconductivity occurs, which is explained by electron trapping by deep states.

    Calculations are presented for the photoluminescence spectrum of InP/In[sub 0.53]Ga[sub 0.47]As superlattices doped with Si. When doping is confined to the inner barriers, the photoluminescence is dominated by transitions between Tamm states in the electron and valence bands, which contribute...

    We report on a broadband GaAs/AlAs superlattice detector for THz radiation; a THz field reduces the current through a superlattice, which is carried by miniband electrons, due to modulation of the Bloch oscillations of the miniband electrons. We studied the detector response, by use of a free...
