The facet degradation reduction electrode 50 is electrically isolated from a forward bias electrode 40. The facet degradation reduction electrode 50 is used to establish an electric field sufficient to reduce facet degradation. In one embodiment, this electric field is established by applying a reverse-bias voltage VRB between the facet degradation reduction electrode 50 and the reference electrode 32. In another embodiment, this electric field is established by electrically connecting the facet degradation reduction electrode 50 to the reference electrode 32.
