Superior Adhesion of Monolayer Amorphous Carbon to Copper

Advanced Materials, EarlyView.
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

Advanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

Advanced Materials, EarlyView.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Unraveling the Complexity of the Dzyaloshinskii–Moriya Interaction in Layered Magnets: The Full Magnitude and Chirality Control

Advanced Materials, EarlyView.
In layered magnets, the atomistic Dzyaloshinskii–Moriya interaction (DMI) depends critically not only on the orbital occupancy of the interface layer but also on the sequence of the atomic layers. The effect can be understood by analyzing the contributions of different orbitals to DMI.

Charge Transport and Carrier Polarity Tuning by Electrolyte Gating in Nickel Benzenehexathiol Coordination Nanosheets

Advanced Materials, EarlyView.
This work reveals that charge transport in nickel benzenehexathiol coordination nanosheets is governed by variable‐range hopping reflecting structural disorder. Electrolyte gating induces a switch in dominant carrier polarity from p‐type to n‐type and leads to an improvement in thermoelectric performance.
