In this paper, the principle of discharge-based pulsed I–V technique is introduced. By using it, the energy and spatial distributions of electron traps within the 4-nm HfO₂ layer have been extracted. Two peaks are observed, which are located at ?E ^-1.0 eV and-1.43 eV, respectively. It is found that the former one is close to the SiO₂/HfO₂ interface and the latter one is close to the gate electrode. It is also observed that the maximum discharge time ha...
