Intersubband transitions in piezoelectric superlattices

Charge-density and spin-density intersubband transitions of electrons in [100] and [111] GaSb/AlSb multiple quantum wells have been measured with inelastic light scattering. These measurements indicate that large built-in electric fields exist in the [111] oriented samples because of the piezoelectr...

Description
Summary:Charge-density and spin-density intersubband transitions of electrons in [100] and [111] GaSb/AlSb multiple quantum wells have been measured with inelastic light scattering. These measurements indicate that large built-in electric fields exist in the [111] oriented samples because of the piezoelectric effect. Furthermore, these built-in fields can be screened by the optical generation of an electron-hole plasma.
