  • Abstract
    The effect of an undoped GaAs spacer layer at the heterojunction interface of MBE-grown n-AlxGa1-xAs/p+-GaAs diodes has been investigated by electroluminescence, dynamic secondary ion mass spectrometry and current/voltage measurements. A consistent picture emerges of the role of the spacer layer in accommodating beryllium migration. A simple procedure to optimise the spacer layer thickness is suggested.
