摘要
An Al(130 nm)/Ni(30 nm)/Ge(40 nm) layer deposited onto n-type GaAs by thermal evaporation was electrically studied. The electrical properties of these contacts were characterized by current-voltage curves and contact noise measurements. The samples have been annealed for different times at different temperatures in flowing forming gas, H-2:N-2 (50%:95%), in a tube furnace. The I-V characteristics of the AlNiGe samples annealed at different temperatures show Schottky character. The I-V plots of the samples that had high noise indexes show a double slope structure.
