As-deposited ferroelectric HZO on a III–V semiconductor [PDF]

Applied Physics Letters, 2022
By electrical characterization of thin films deposited by atomic layer deposition, HfxZr1−xO2 (HZO) is shown to be ferroelectric as-deposited, i.e., without any annealing step, using a thermal budget of 300 °C. By fabricating laminated HZO films rather than the traditional solid-solution HZO, a remanent polarization of Pr = 11 μC/cm2 and endurance ...

Associative Learning Emulation in HZO-Based Ferroelectric Memristor Devices

Materials
Neuromorphic computing inspired by biological synapses requires memory devices capable of mimicking short-term memory (STM) and associative learning. In this study, we investigate a 15 nm-thick Hafnium zirconium oxide (HZO)-based ferroelectric memristor device, which exhibits robust STM characteristics and successfully replicates Pavlov’s dog ...

Study of structural and electrical properties of ferroelectric HZO films obtained by single-target sputtering

AIP Advances, 2021
In this work, we study the structural and electrical properties of Hafnium Zirconium Oxide (HZO) thin films deposited by Hf0.5Zr0.5O2 single-target sputtering to fabricate a TiN/(14-/22 nm-thick) HZO/TiN stack.

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.

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.

Characteristics of Hf_0.5Zr_0.5O₂ Thin Films Prepared by Direct and Remote Plasma Atomic Layer Deposition for Application to Ferroelectric Memory

Nanomaterials, 2023
Hf0.5Zr0.5O2 (HZO) thin film exhibits ferroelectric properties and is presumed to be suitable for use in next-generation memory devices because of its compatibility with the complementary metal–oxide–semiconductor (CMOS) process.

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.
