An evaluation of the effect of interfacial reactions on the electrical properties of a polycrystalline Si1-xGex/HfO2 gate stack was performed. It was found that the results were compared with those of a conventional poly-Si/HfO2 system. Results showed that the differences in reactions between a poly-Si0.4Ge 0.6/HfO2 and a poly-Si/HfO2 interface were due to the accumulation of Ge.
