we mainly review the recent scanning tunneling microscopy(STM)advances on the spin and/or valley polarized states induced by an individual atomicscale defect in graphene,including a single-carbon vacancy,a nitrogen-atom dopant,and a hydrogen-atom chemisorption.Lastly,we give a perspective in this ...
4a). In other words, Co N4(O) retains most of its high catalytic activity and is more inclined to produce H2O2. Based on this result, the Co1-NG(O) catalysts obtained by using graphene oxide (GO) containing oxygen-rich functional groups to support Co single atoms are designed to have ...
binding energy than the defect-freenanotubewith adsorbing two H2molecules, which is desirable for practical applications [138]. The interaction of hydrogen with defective chemically produced graphene, obtained by thermal expansion of graphiteoxide, has been investigated in detail by Pontiroli et al. ...
Defect formation energies of the defect qubits foraNCVC−1in diamond,bCBVNin hBN in N-rich condition, andcWSein MoSe2in Mo-rich condition. The M-rich condition for MX2(N-rich condition for hBN) provides lower defect formation energies than the X-rich condition (B-rich condition) (Supplem...
Gábor Zsolt Magda1,*, János Pető1, Ji-Young Noh2,Yong-Sung Kim2, Chanyong Hwang2, László P. Biró3 & Levente Tapasztó1 MoS2 single layers have recently emerged as strong competitors of graphene in electronic and optoelectronic device applications due to their intr...

80 AFM is widely used in graphene research to characterize graphene topography, size, thickness, and atomic defects, by following the movement of a cantilever on the graphene surface, relative to that on the substrate itself.81 Moreover, mechanical and electronic properties of graphene (composites)...
Non-volatile resistive switching, also known as memristor1 effect, where an electric field switches the resistance states of a two-terminal device, has emerged as an important concept in the development of high-density information storage, computing and reconfigurable systems2,3,4,5,6,7,8,9. ...
