Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="pssa201330357-sec-0001" sec-type="section"> <p>The interface formation between epitaxial CuInSe₂(112) films and ZnO deposited by metal‐organic MBE is investigated by photoelectron spectroscopy. Reaction of diethyl‐zinc with CuInSe₂ leads to the formation of an intrinsic ZnSe layer and copper depletion of the interface. This is associated with Zn doping of the chalcopyrite surface and a Fermi‐level shift toward the conduction band. The implications on the band alignment are discussed.</p> </sec> </abstract>
