A silicon-based interband tunneling diode (10, 110) includes a degenerate p-type doping (22, 130) of acceptors, a degenerate n-type doping (32, 118) of donors disposed on a first side of the degenerate p-type doping (22, 130), and a barrier silicon-germanium layer (20, 136) disposed on a second side of the degenerate p-type doping (22, 130) opposite the first side. The barrier silicon-germanium layer (20, 136) suppresses diffusion of acceptors away from a p/n junction defined by the degenerate p-type and n-type dopings (22, 32, 118, 130).
