  • The monolayer transition-metal dichalcogenide molybdenum disulphide has recently attracted attention owing to its distinctive electronic properties. Cao and co-workers present numerical evidence suggesting that circularly polarized light can preferentially excite a single valley in the band structure of this system.

  • The superconducting critical temperature of monolayer materials is often lower than their bulk counterparts. Now, intercalation is shown to induce two-dimensional superconducting properties while maintaining the bulk critical temperature.

  • A novel ultra-thin-walled ZnO microtube cavity with a wall thickness of ~750 nm, supporting multiple types of optical modes, including in-tube Fabry–Perot modes, in-wall Fabry–Perot modes and wave-guided whispering gallery modes is fabricated via optical vapor supersaturated precipitation. The intensities of near-band edge and X-band emission are therefore increased at least one order of magnitude in the temperature range of 0–500 °C. The ultra-thin-walled ZnO microtube demonstrates unprecedented applications, for example, temperature-sensitive multicolor luminescence, low-threshold ultravoilet (UV) lasing and high-performance recyclable on-chip photodegradation, within one platform. It provides new opportunities to design multifunctional tailored wide bandgap semiconductor devices for a variety of optoelectronic applications in micro/nanophotonics.
