Bi-induced layer exchange crystallization for low-temperature formation of n-type Ge on insulator.For Ge/Bi (100/100nm) stacked structures, layer exchange is achieved at 250-400 degrees.The free electron concentration (about 1019cm-3) of the grown layer is significantly larger than the thermal equilibrium solid solubility.
