TL;DR: This work reports the observation of domains on exfoliated monolayer graphene that differ by their friction characteristics, as measured by friction force microscopy, and proposes that the domains arise from ripple distortions that give rise to anisotropic friction in each domain as a result of the an isotropic puckering of the graphene.

TL;DR: In this paper, the authors proposed a method for the realization of next-generation electronic devices based on the transport properties of monolayer graphene, which is one of the most interesting materials applicable to next generation electronic devices due to its transport properties.

TL;DR: This work reports on nanoscale hydrogenation and oxidation of graphene under normal atmospheric conditions and at room temperature without etching, wet process, or even any gas treatment by controlling just an external bias through atomic force microscope lithography.

TL;DR: In this paper, the authors investigated water diffusion between monolayer graphene and SiO2 under high humidity conditions using atomic force microscopy and found that water diffuses into graphene/SiO2 and forms an ice-like structure up to two layers thick.

TL;DR: B bipolar resistive switching behaviours of nano-crystalline BiFeO3 (BFO) nano-islands grown on Nb-doped SrTiO3 substrates are reported, showing both high resistance ratio and nonlinearity factor offers a simple and promising building block of high density ReRAM.
