Evolution of interface chemistry and dielectric properties of HfO2/Ge gate stack modulated by Gd incorporation and thermal annealing

In current work, effects of rapid thermal annealing (RTA) on the interface chemistry and electrical properties of Gd-doped HfO2 (HGO)/Ge stack have been investigated systematically. It has been demonstrated that the presence of GeOx interfacial layer between HfGdO and Ge is unavoidable and appropria...
