A [ital p][sup +]-AlGaAs/[ital n][sup +]-GaInP heterojunction tunnel diode with band gap [ital E][sub [ital g]][approx]1.9 eV was fabricated by Atomic Layer Epitaxy growth mode using carbon and selenium as the [ital p]- and [ital n]-type dopants, respectively. The doping levels of 1[times]10[sup 20]/cm[sup 3] and 5[times]10[sup 19]/cm[sup 3] were achieved both in the [ital p]- and [ital n]-side of the diode, respectively. The diode can be used as the interconnection of the high and low band gap cells in the AlGaAs/GaAs cascade solar cell structure. At the forward current of 15 A/cm[sup 2], which is the expected current density at 1000 suns operation, there is only [similar to]17 mV voltage drop across the tunnel junction. This is the first reported tunnel diode fabricated in high band gap material systems, with performances that exceed the best reported GaAs tunnel diode.
