Researchers devise tunable conducting edge

Physicists demonstrated a new magnetized state in a monolayer of tungsten ditelluride. Called a magnetized or ferromagnetic quantum spin Hall insulator, this material of one-atom thickness has an insulating interior but a conducting edge, which has important implications for controlling electron flow in nanodevices.

A memristive forming strategy for lowering the contact resistances of two-dimensional semiconductors

Two-dimensional (2D) semiconductors, like transition-metal dichalcogenides, have become a competitive alternative to traditional semiconducting materials in the post-Moore era, and caused worldwide interest. However, before they can be used in practical applications, some key obstacles must be resolved. One of them is the large electrical contact resistances at the metal-semiconductor interfaces. Researchers have proposed a brand-new contact resistance lowering strategy of 2D semiconductors with a good feasibility, a wide generality and a high stability.

Van der Waals infrared photodetectors based on 'optical' and 'electrical' combined manipulations

Blackbody response is highly desired in two-dimensional (2D) infrared photodetectors, which determines their practical applications. However, limited by the thickness and complex defects of 2D materials, 2D photodetectors still suffer from problems such as low quantum efficiency and large dark current. Researchers now demonstrate fully depleted self-aligned van der Waals (vdW) photodetectors based on a heterosandwiched structure.
