The ultraviolet-assisted intercalative oxidation of high-mobility two-dimensional semiconductor Bi2O2Se can be used to create a single-crystalline native oxide dielectric—β-Bi2SeO5—that can yield top-gated transistors with an equivalent oxide thickness of 0.41 nm.

A monocrystalline native oxide dielectric, β-Bi2SeO5, with a high dielectric constant has been synthesized by oxidizing a two-dimensional (2D) semiconductor, Bi2O2Se. In 2D transistors, the ultrathin β-Bi2SeO5 dielectric demonstrates sub-0.5-nm equivalent oxide thickness and leakage current below the low-power limit, meeting the requirements of the International Roadmap for Devices and Systems.

The authors use circularly polarized light pulses to trigger all-optical magnetization switching in an atomically thin ferromagnetic semiconductor. The switching process is related to spin angular momentum transfer from photoexcited carriers to local magnetic moments.

On-surface synthesis enables highly reactive structures to be produced under vacuum, but they need to be passivated to be incorporated into practical devices. Here, the facile protection of air-sensitive chiral graphene nanoribbons has been shown, by either hydrogenation or synthesis of an oxidized form. The chemically stable forms can subsequently be deprotected.

Current synthesis of 2D crystalline superconductors mainly limits them to layered materials. Now, crystalline, non-layered 2D PdTe has been synthesized by inducing interfacial reactions at a solid–solid interface, exhibiting 2D superconductivity with a thickness-dependent onset critical temperature of ~2.56 K.
