Abstract : Doping with one of the group Ia elements Li, Na or K near the heteroface junction produced P+ conductivity in the gallium arsenide and N+ conductivity in the germanium. The device can be used, for example, as a dual bandgap solar cell. The fabrication includes implanting the group Ia dopant in a Ge wafer. This dopant diffuses into the GaAs when it is subsequently deposited on the Ge.
