Refining Au/Sb alloyed ohmic contacts in undoped Si/SiGe strained quantum wells
Journal ArticlePublisher:Journal of Physics: Condensed MatterDate:2025Authors:Lucky Donald L KynshiUmang SoniChithra H SharmaShengqiang ZhouMadhu ThalakulamDescription:This work addresses the challenges of implementing Au/Sb as an ohmic contact to an undoped Si/SiGe system and presents a simple recipe to establish high-efficiency contacts to realize shallow enhancement mode devices. The electrical characteristics of the alloyed contacts are similar to those realized by phosphorus ion-implantation, suggesting that this method can serve as an alternative method for the realization of quantum devices on shallow undoped Si/SiGe heterostructures.
