Abstract

We report on electron photo-injection results in HfO2 films using capacitance vs. voltage (CV) and electron spin resonance measurements. CV measurements indicate presence of pre-existing large capture cross section electron traps. Electron spin resonance measurements indicate trapped electrons in the form of O-2 superoxide ions. Another center, likely a Hf+3 center, is also observed.
