Characterization of HZO Films Fabricated by Co-Plasma Atomic Layer Deposition for Ferroelectric Memory Applications

Nanomaterials
Plasma-enhanced atomic layer deposition (ALD) is a common method for fabricating Hf0.5Zr0.5O2 (HZO) ferroelectric thin films that can be performed using direct-plasma (DP) and remote-plasma (RP) methods.

Cryogenic Ferroelectricity of HZO Capacitors on a III-V Semiconductor

IEEE Electron Device Letters
Non-volatile cryogenic memories are crucial for realizing energy-efficient and scaled quantum computing systems. In this letter, we evaluate the cryogenic performance of an HZO-based ferroelectric capacitor (FeCAP) with a compound semiconductor (InAs) as

HZO-based FerroNEMS MAC for in-memory computing

Applied Physics Letters, 2022
This paper demonstrates a hafnium zirconium oxide (HZO)-based ferroelectric NEMS unimorph as the fundamental building block for very low-energy capacitive readout in-memory computing. The reported device consists of a 250×30 μm2 unimorph cantilever with 20-nm-thick ferroelectric HZO on 1 μm SiO2.

RF-Characterization of HZO Thin Film Varactors [PDF]

Crystals, 2021
A microwave characterization at UHF band of a ferroelectric hafnium zirconium oxide metal-ferroelectric-metal (MFM) capacitors for varactor applications has been performed. By using an impedance reflectivity method, a complex dielectric permittivity was obtained at frequencies up to 500 MHz.

A Rare Complication of Herpes Zoster Ophthalmicus (HZO)

Cureus, 2023
Retrobulbar optic neuritis is a rare complication of herpes zoster ophthalmicus (HZO). We report a case of a 27-year-old man who presented with a progressive left blurring of vision for one week. A history of vesicular rashes in the left trigeminal nerve area preceded his condition.
