A Cu/HZO/GeS/Pt Memristor for Neuroinspired Computing
physica status solidi (RRL) – Rapid Research Letters, 2021Recently, resistive random access memory (RRAM) has become an important device for nonvolatile memory and neuromorphic computing. Herein, Cu/Hf0.5Zr0.5O2 (HZO)/GeS/Pt and Cu/GeS/Pt devices are fabricated and the electrical characteristics are compared in detail. The experimental results show that the when one oxide layer HZO is inserted into the Cu/GeS/

Effects of shear strain on HZO ferroelectric orthorhombic phases
Applied Physics Letters, 2023The stabilities of hafnium and zirconium oxide ferroelectric orthorhombic phases, oIII-phase (Pca21) and oIV-phase (Pmn21), under shear strain are investigated theoretically by atomic modeling with density functional theory calculations. The results indicate that oIV-phase serves as a buffer state preventing oIII-phase from transforming into m-phase ...

Recurrent VZV Epithelial Keratitis in HZO; HZO sine Herpete
2010In some patients with HZO, VZV epithelial keratitis recurs. In the present patients, recurrent lesions were indistinguishable from those observed during the HZO episode; both their morphology and their dynamics appeared identical. Such recurrences are less well known but might be more common than suspected.

Herpes Zoster Ophthalmicus (HZO) Keratitis
2020Herpes Zoster Ophthalmicus (HZO) is caused by reactivation of latent Varicella zoster virus in the ophthalmic branch of the trigeminal ganglion. Typically, this occurs in the elderly but is increasingly occurring in younger individuals. It starts with pain in the distribution of the nerve followed by dermatitis.

Applied Physics Letters
In this Letter, we demonstrate an enhanced switching speed of 589 ns and a superior double remanent polarization of 40.38 μC/cm2 under a low operating voltage of 2.0 V in the ferroelectric HZO/ZrO2/HZO stack compatible with the back-end of line process. This enhancement in ferroelectricity and switching speed is attributed to an improved fraction of FE
