Hafnium Dioxide Nanoparticle Thin Film Morphology and Reactivity with Dimethyl Methylphosphonate
… reactions that occur on the surface of hafnium dioxide. Metal oxide and metal-oxide nanoparticles have been shown to decompose organophosphonate molecules. In this study, high surface area hafnium oxide nanoparticles are synthesized via laser ablation. This creates nanoparticles that are …

Next-Generation Flash Memories Using Two-Dimensional Materials
… (FGT) based on the proposed model. Silicon dioxide (SiO₂) and Hafnium dioxide (HfO₂) are the two oxides explored as the top control oxide of the device.

Deposition and characterization of HfO₂ thin films
Hafnium Dioxide(HfO₂) thin films were deposited on glass, metal, and silicon wafer substrates using magnetron RF reactive sputtering techniques. Structure and morphology of the thin films were investigated by x-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron …

Germanium on Silicon Integrated Photonics for the Mid-Wave Infrared
… is conducted including niobium pentoxide, hafnium dioxide, epitaxial silicon, and others. Of these materials, niobium pentoxide offers the best performance with measured losses as low as 3.49±0.3 dB/cm. A passive component library is designed based on waveguides with and without top …

The high temperature structural evolution of hafnia
The transformations of HfO2 are often described as analogous with the transformations in ZrO2 because of the similar crystal structures; however the phase transformations in HfO2 occur at higher temperatures. Even though this phase transformation has been extensively studied in ZrO2 , the …
