Abstract

We have observed a substantial blue shift of the lowest energy transition in a composite double quantum well made from materials with a type-TI band line-up. The pho tocurrent measurements demonstrate a linear Stark shift due to the separate confinement in real space for electrons and holes. The charge separation is up to 45 Å in the strain bal anced InAs0.42P0.58/Gao.67In0.33As samples. The low tem perature photoluminescence reveals that an electric field of only 30 kV/cm produces the blue shift of more than 25 meV. All our measurements agree with the calculations within the framework of Bir-Pikus strain Hamiltonian.
