Investigation of Electrical Characteristics of NdAlO3/SiO2 Stack Gate
Degradation of electrical characteristics of NdAKVSiO2 stack gate under the constant voltage stress (CVS) is presented. It is found that the electron trapping, positive charges and oxide trap generation acts together, which causes the degradation of NdAlO3/SiO2 stack gate. The transport mechanisms of the gate leakage current in NdAlO3/SiO2 stack gate are also investigated. Frenkel-Poole emission and Schottky emission are the main transport mechanisms of the gate leakage current for the fresh sample, while F-N tunneling and Schottky emission are responsible for the gate leakage current after stress.
