Abstract
The formation and characterization of nanometer-size, ohmic contacts to ��n-type GaAs substrates are described. The nanocontacts are formed between a single-crystalline, nanometer-size Au cluster and a GaAs structure capped with layer of low-temperature-grown GaAs (LTG:GaAs). An organic monolayer of xylyl dithiol (p(p-xylene-α,α′α,α′- dithiol; C8H10S2)C8H10S2) provides mechanical and electronic tethering of the Au cluster to the LTG:GaAs surface. The I(V)I(V) data of the Au cluster/xylyl dithiol/GaAs show ohmic contact behavior with good repeatability between various clusters distributed across the surface. The specific contact resistance is determined to be 1×10 −6 Ω cm 2. Current densities above 1×106A/cm2 have been observed.
