摘要
On the basis of the experimental results of XPS analysis and the carrier separation, the band diagram and carrier transport mechanism in ZrO2 dielectrics were clarified for the first time. ZrO2-MIS structure consists of ZrO2 layer and the interfacial Zr-silicate layer. The carrier conduction in ZrO2 layer is dominant in the ZrO2/Zr-silicate/Si MIS structure. It was found that the hole conduction mechanism is different from electron conduction mechanism in ZrO2 gate dielectrics.
