Anomalous piezoelectricity in two-dimensional graphene nitride nanosheets.
Piezoelectricity is a unique property of materials that permits the conversion of mechanical stimuli into electrical and vice versa. On the basis of crystal symmetry considerations, pristine carbon nitride (C3N4) in its various forms is non-piezoelectric. Here we find clear evidence via piezoresponse force microscopy and quantum mechanical calculations that both atomically thin and layered grap...
متن کاملPiezoelectricity in two-dimensional group-III monochalcogenides
KEYWORDS piezoelectricity, two-dimensional (2D) material, monochalcogenide, density functional theory (DFT) calculation ABSTRACT It is found that several layer-phase group-III monochalcogenides, including GaS, GaSe, and InSe, are piezoelectric in their monolayer form. First-principles calculations reveal that the piezoelectric coefficients of monolayer GaS, GaSe, and InSe (2.06, 2.30, and 1.46 ...

SYNTHESIS AND FUNCTIONALIZATION OF ATOMIC LAYER BORON NITRIDE NANOSHEETS FOR ADVANCED MATERIAL APPLICATIONS Report Title Besides graphene, hexagonal boron nitride nanosheets (BNNSs) are playing an excellent role for the next generation of 2-dimentional (2D) functional nanomaterials. Due to the similar lattice parameter and identical crystalline structure to that of graphene, BNNSs are often kno...
متن کاملLuminomagnetic bifunctionality of Mn(2+)-bonded graphene oxide/reduced graphene oxide two dimensional nanosheets.
Herein, we report the luminomagnetic bifunctional properties of two-dimensional (2D) Mn(2+) bonded graphene oxide (GO)/reduced graphene oxide (RGO) nanosheets synthesized using a facile route of oxidation followed by a solvothermal reduction method. Photoluminescence (PL) studies (excited by different wavelengths) revealed that the resonant energy transfer between Mn(2+) and sp(3)/sp(2) cluster...
