TL;DR: The fabrication of large-area high-quality 2D ultrathin α-Mo2C crystals by chemical vapour deposition (CVD) that show 2D characteristics of superconducting transitions that are consistent with Berezinskii-Kosterlitz-Thouless behaviour and show strong anisotropy with magnetic field orientation.

TL;DR: The wrinkle-free graphene shows enhanced electrical mobility compared to graphene with wrinkles and the transfer of an ultraflat graphene film onto target substrates from the reusable single-crystal Cu(111)/sapphire growth substrate is demonstrated.

TL;DR: The authors elucidate the origin of contaminations in CVD-grown graphene and devise a strategy towards the scalable production of ultra-clean graphene with >99% clean regions and low contact resistance.

TL;DR: Wafer-sized single-crystalline Cu (100) surface can be readily achieved on stacked polycrystaline Cu foils via simple oxygen chemisorption-induced reconstruction, enabling fast growth of large-scale millimeter-sizedsingle-cry crystalline graphene arrays under molecular flow.

TL;DR: The direct growth of high-quality graphene/2D superconductor (nonlayered ultrathin α-Mo2C crystal) vertical heterostructures with uniformly well-aligned lattice orientation and strong interface coupling by chemical vapor deposition are reported.
