A heterostructure interband tunneling diode includes a contact layer comprising indium gallium arsenide of a first conductivity type, an injection layer comprising indium gallium arsenide of a second conductivity type, a first doped layer of the first conductivity type positioned adjacent to the contact layer, and a second doped layer of a second conductivity type juxtaposed between the first doped layer and the injection layer, wherein at least one of the first and second tunnel barrier layers comprises indium aluminium arsenide. A second embodiment includes a doped layer of the first conductivity type positioned adjacent to the contact layer, and a barrier layer positioned adjacent to the injection layer, and a quantum well layer comprising indium gallium arsenide juxtaposed between the doped layer and the barrier layer, wherein at least one of the doped and barrier layers comprises indium aluminium arsenide.
