GaAs pn diodes with heavily carbon-doped p-type GaAs grown by MOMBE were fabricated. The I-V and C-V characteristics were not significantly affected by the hole concentration of the p-GaAs although a lattice mismatch at the junction generates misfit dislocations. A good I-V characteristic with [...]
