Webmaterials Article Structural, Optical and Electrical Properties of HfO2 Thin Films Deposited at Low-Temperature Using Plasma-Enhanced Atomic Layer Deposition WebHfO 2 has promising applications in semiconductors and optics due to its high dielectric constant and high refractive index. In this work, HfO 2 thin films were deposited by plasma enhanced atomic layer deposition (PEALD) using tetrakis-dimethylamino hafnium (TDMAH) and oxygen plasma.
