The impact of lanthanum (La) on positive-bias temperature instability (PBTI) is examined via first-principles simulation of the electronic properties of the oxygen vacancy (VO) and vacancy-interstitial (VO-Oi) paired defects in the hafnium dioxide (HfO2) gate dielectric. The purpose is to understand...
