Current silicon-based CMOS devices face physical limitations in downscaling size and power loss, restricting their capability to meet the demands for data storage and information processing of emerging technologies. One possible alternative is to encode the information in a non-volatile magnetic state and manipulate this spin state electronically, as in spintronics. However, current spintronic devices rely on the current-driven control of magnetization, which involves Joule heating and power dissipation.

Following the recent emphasis on supervisory interactions in abusive supervision, this study explains why and how supervisors' job insecurity and authoritarianism are related to abusive supervision and how subordinates' characteristics, agreeableness and negotiating resistance interact with the effects of supervisors' characteristics. We conducted a field study with 261 supervisor and subordinate dyads in South Korea, and the study findings confirmed that supervisors' authoritarianism is positively related to abusive supervision and that the effect is enhanced when subordinates are highly agreeable and display resistant behaviors. The study contributes to the leadership literature, particularly on abusive supervision and personality.

High-performance p-type two-dimensional (2D) transistors are fundamental for 2D nanoelectronics. However, the lack of a reliable method for creating high-quality, large-scale p-type 2D semiconductors and a suitable metallization process represents important challenges that need to be addressed for future developments of the field. Here, we report the fabrication of scalable p-type 2D single-crystalline 2H-MoTe transistor arrays with Fermi-level-tuned 1T'-phase semimetal contact electrodes.

High-performance van der Waals (vdW) integrated electronics and spintronics require reliable current-carrying capacity. However, it is challenging to achieve high current density and air-stable performance using vdW metals owing to the fast electrical breakdown triggered by defects or oxidation. Here, we report that spin-orbit interacted synthetic PtTe layers exhibit significant electrical reliability and robustness in ambient air.
