The growth and characterization of germanium interconnects is described in this paper. Resistivity measurements indicate that n +-GaAs/p +-Ge/p +-GaAs structures may be the most viable interconnect yet reported for monolithic cascade cells. Specific interface resistivities as low as 1 × 10 −4 Ω cm 2...
