Electrical characterization of HfO2 MOSFETs with La 2O3 incorporation has been conducted. A shift in threshold voltage to negative direction has been observed with La2O 3 incorporation. Moreover, gm and subthreshold slope have been improved with La2O3. 1/f noise measurement has revealed that HfO2 gated MOSFET incorporating La2O 3 layer reduces the noise level .
