TL;DR: In graphene heterostructures, the edge-contact geometry provides new design possibilities for multilayered structures of complimentary 2D materials, and enables high electronic performance, including low-temperature ballistic transport over distances longer than 15 micrometers, and room-tem temperature mobility comparable to the theoretical phonon-scattering limit.

TL;DR: Ballistic transport of electrons at room temperature in top-gated InAs nanowire (NW) transistors is experimentally observed and theoretically examined and the mean free path is found to be independent of temperature due to the dominant role of surface roughness scattering.

TL;DR: The effective electron mobility of InAs QMs is shown to exhibit anomalous field and thickness dependences that are in distinct contrast to the conventional MOSFET models, arising from the strong quantum confinement of carriers.

TL;DR: Wang et al. as discussed by the authors evaluated the geographic distributions of bacterial diversity and their driving factors across nine latitudinal forests along a 3,700-km north-south transect in eastern China, using high-throughput 16S rRNA gene sequencing.

TL;DR: Using a multifactorial global change experiment, the authors show that warming grassland plots by +3 °C over 6 years accelerates the scaling rate of both taxonomic and phylogenetic diversity in soil bacterial and fungal communities.
