Graphdiyne and its Assembly Architectures: Synthesis, Functionalization, and Applications

Publications on 2D Materials - 3 hours 5 min ago

Recent progress on graphdiyne, with its fascinating structure and physical and chemical properties, is summarized. Research efforts toward controllable electronic structure, chemical modification, and applications of graphdiyne in different research fields and corresponding mechanisms are discussed, and critical research insights into the future development of graphdiyne materials are proposed and presented. Abstract Graphdiyne (GDY), a novel one‐atom‐thick carbon allotrope that features assembled layers of sp‐ and sp2‐hybridized carbon atoms, has attracted great interest from both science and industry due to its unique and fascinating structural, physical, and chemical properties. GDY‐based materials with different morphologies, such as nanowires, nanotube arrays, nanosheets, and ordered stripe arrays, have been applied in various areas such as catalysis, solar cells, energy storage, and optoelectronic devices. After an introduction to the fundamental properties of GDY, recent advances in the fabrication of GDY‐based nanostructures and their applications, and corresponding mechanisms, are covered, and future critical perspectives are also discussed.

Chemical Doping: Chemically Tuned p‐ and n‐Type WSe2 Monolayers with High Carrier Mobility for Advanced Electronics (Adv. Mater. 42/2019)

Publications on 2D Materials - 3 hours 6 min ago

In article number https://doi.org/10.1002/adma.2019036131903613, Hiroki Ago and co‐workers demonstrate the chemical‐doping‐induced conversion of ambipolar WSe2 monolayers to p‐ and n‐type semiconductors. The chemical doping not only allows control over the main carriers, but also significantly increases the carrier mobility. By integrating the chemically doped WSe2, a CMOS inverter and an in‐plane p–n junction with superior performance are successfully fabricated.

Tunable valley Hall effect in gate-defined graphene superlattices

Publications on 2D Materials - 5 hours 8 min ago

Author(s): Johannes H. J. Martiny, Kristen Kaasbjerg, and Antti-Pekka JauhoWe theoretically investigate gate-defined graphene superlattices with broken inversion symmetry as a platform for realizing tunable valley-dependent transport. Our analysis is motivated by recent experiments [C. Forsythe et al., Nat. Nanotechnol. 13, 566 (2018)] wherein gate-tunable superlattice po…[Phys. Rev. B 100, 155414] Published Tue Oct 15, 2019
