ZnSe-GaAs(001) heterostructures have been grown by molecular beam epitaxy and characterized in situ by means of reflection high energy electron diffraction and x-ray photoemission spectroscopy, and ex-situ by near edge photoluminescence spectroscopy and by cross sectional transmission electron microscopy. By changing the Zn/Se flux intensity ratio we were able to control the Zn/Se relative concentration in the interface region, while maintaining a similar structure and high degree of long range order of the interface.
