An electronic device contains a substrate, a sub-collector supported by the substrate, an un-doped layer having a selectively implanted buried sub-collector and supported by the sub-collector, an As-based nucleation layer partially supported by the un-doped layer, a collector layer supported by the As-based nucleation layer, a base layer supported by the collector layer, an emitter layer and a base contact supported by the base layer, an emitter cap layer supported by the emitter layer, an emitter contact supported by the emitter cap layer, and a collector contact supported by the sub-collector. A method provides for selecting a first InP layer, forming an As-based nucleation layer on the first InP layer, and epitaxially growing a second InP layer on the As-based nucleation layer.
