A strong electro-optically active lead-free ferroelectric integrated on silicon

The strong electro-optical response of BaTiO₃ could be useful for making high-speed switches for optical telecommunications. Abel et al. demonstrate the ability to maintain this response in BaTiO₃films grown directly onto silicon, extending its potential to the development of silicon photonics.

Intrinsic negative magnetoresistance from the chiral anomaly of multifold fermions

Multifold fermions promise a solid-state platform for accessing and studying the effects of the chiral anomaly beyond Weyl fermions. Here, the authors identify multifold fermions in magnetotransport in the chiral semimetal CoSi.

High-speed III-V nanowire photodetector monolithically integrated on Si

Direct epitaxial growth of III-V on Si for optical emitters and detectors remains a challenge. Here, the authors demonstrate in-plane monolithic integration of an InGaAs nanostructure p-i-n photodetector on Si capable of high-speed optical data reception at 32 Gbps enabled by a 3 dB bandwidth exceeding 25 GHz.

Waveguide coupled III-V photodiodes monolithically integrated on Si

To realize on-chip optical communication schemes based on silicon, the integration of waveguides onto III-V devices must be achieved. Here, the authors report waveguide-coupled III-V heterostructure photodiodes monolithically integrated on silicon waveguides via aligned nanowire.

Nanoelectrical analysis of single molecules and atomic-scale materials at the solid/liquid interface

The use of a gold substrate coated with organic monolayers and a highly viscous immobilizing liquid allows the characterization of the electronic properties of carbon-based materials deposited on the coated substrates at the solid/liquid interface.
