Low Resistance, Unannealed ohmic Contacts to n-Type InAs0.66Sb0.34
Abstract
Unannealed Ti/Pt/Au contacts to n-type InAs(0.66)Sb(0.34) were fabricated and measured. Extremely low specific contact resistances down to 2.4 x 10(-8) Omega cm(2) were measured, commensurate with In(0.53)Ga(0.47)As, InAs, and In(0.27)Ga(0.73)Sb contact schemes with higher doping, which is due to the very high electron mobility in InAs(0.66)Sb(0.34) and hypothesised pinning of the surface Fermi level within the conduction band.
