Synergistic Approach of Interfacial Layer Engineering and READ-Voltage Optimization in HfO-Based FeFETs for In-Memory-Computing Applications.

This article reports an improvement in the performance of the hafnium oxide-based (HfO) ferroelectric field-effect transistors (FeFET) achieved by a synergistic approach of interfacial layer () engineering and -voltage optimization. FeFET devices with silicon dioxide (SiO) and silicon oxynitride (SiON) as were fabricated and characterized. Although the FeFETs with SiO interfaces demonstrated better low-frequency characteristics compared to the FeFETs with SiON interfaces, the latter demonstrated better endurance and retention.

Structural and Electrical Response of Emerging Memories Exposed to Heavy Ion Radiation.

Hafnium oxide- and GeSbTe-based functional layers are promising candidates in material systems for emerging memory technologies. They are also discussed as contenders for radiation-harsh environment applications. Testing the resilience against ion radiation is of high importance to identify materials that are feasible for future applications of emerging memory technologies like oxide-based, ferroelectric, and phase-change random-access memory.

Electric field-induced crystallization of ferroelectric hafnium zirconium oxide.

Ferroelectricity in crystalline hafnium oxide thin films is strongly investigated for the application in non-volatile memories, sensors and other applications. Especially for back-end-of-line (BEoL) integration the decrease of crystallization temperature is of major importance. However, an alternative method for inducing ferroelectricity in amorphous or semi-crystalline hafnium zirconium oxide films is presented here, using the newly discovered effect of electric field-induced crystallization in hafnium oxide films.

Structural and Electrical Comparison of Si and Zr Doped Hafnium Oxide Thin Films and Integrated FeFETs Utilizing Transmission Kikuchi Diffraction.

The microstructure of ferroelectric hafnium oxide plays a vital role for its application, e.g., non-volatile memories.

Peripheral Nerve Injuries in Sport.

Sport-related peripheral nerve injuries (SRNIs) can occur in virtually any sport whether or not enjoyed by an amateur or in the career of a professional athlete. The diagnosis of SRNIs can be difficult, especially when trying to differentiate nerve injury from musculoskeletal pain. Clinicians should be able to recognize when a significant SRNI occurs and how to initiate a diagnostic and treatment pathway and referral to a specialist.

Evaluation of the effectiveness of packed red blood cell irradiation by a linear accelerator.

Irradiation of blood components with ionizing radiation generated by a specific device is recommended to prevent transfusion-associated graft-versus-host disease. However, a linear accelerator can also be used in the absence of such a device, which is the case of the blood bank facility studied herein. In order to evaluate the quality of the irradiated packed red blood cells, this study aimed to determine whether the procedure currently employed in the facility is effective in inhibiting the proliferation of T lymphocytes without damaging blood components.

Adult T-cell leukemia/lymphoma: report of two cases.

Adult T-cell leukemia/lymphoma is a lymphoproliferative disorder of mature T lymphocytes associated with infection with human T-cell lymphotrophic virus type I (HTLV-I). Adult T-cell leukemia/lymphoma is characterized by clinical and laboratory polymorphism that allows it to be classified into four distinct subgroups: smoldering, chronic, acute and lymphomatous types. We present here two cases of adult T-cell leukemia/lymphoma, respectively in the acute and lymphomatous forms of the disease.
