Abstract

The structural integrity, composition and interface quality of tunnel barriers in hybrid ferromagnet-semiconductor structures will have a significant effect on the properties of spintronic devices. We present the results of a study of an amorphous MgO tunnel barrier in a Co/MgO/InAs multilayer structure. Optimum growth parameters for MgO and surface treatment of InAs have been identified by a systematic electron microscopy investigation. Electron energy loss spectroscopy has been used to obtain information on composition and interface quality in the multilayer structures.
