چکیده

The relationship between the electrical properties and structure evolution of single layer graphene was studied by gradually introducing the gallium ion irradiation. Raman spectrums show a structural transition from nano-crystalline graphene to amorphous carbon as escalating the degree of disorder of the graphene sample, which is in correspondence with the electrical transition from a Boltzmann diffusion transport to a carrier hopping transport. The results show a controllable method to tune the properties of graphene.

Unusual surface and edge morphologies, sp to sp hybridized transformation and electronic damage after Ar ion irradiation of few-layer graphene surfaces

Roughness and defects induced on few-layer graphene (FLG) irradiated by Ar ions at different energies were investigated using X-ray photoemission spectroscopy (XPS) and atomic force microscopy techniques. The results provide direct experimental evidence of ripple formation, sp to sp hybridized carbon transformation, electronic damage, Ar implantation, unusual defects and edge reconstructions in...

Swift heavy ion irradiation-induced modifications in structural, magnetic and electrical transport properties of epitaxial magnetite thin films

The effect of swift heavy ion SHI irradiation 190 MeV Ag on structural, electrical transport and magnetic properties of epitaxial magnetite Fe3O4 thin films thickness 70 nm grown on MgO 100 oriented substrate have been investigated. The x-ray diffraction shows that at low fluence values up to 5 1011 ions/cm2, the strain in the films is relaxed, whereas, at higher fluence range 1 1012–1 1013 ion...

In-situ observation and atomic resolution imaging of the ion irradiation induced amorphisation of graphene

Ion irradiation has been observed to induce a macroscopic flattening and in-plane shrinkage of graphene sheets without a complete loss of crystallinity. Electron diffraction studies performed during simultaneous in-situ ion irradiation have allowed identification of the fluence at which the graphene sheet loses long-range order. This approach has facilitated complementary ex-situ investigations...

Electric-Field-Induced Triplet to Singlet Transition in Size-2 Trigonal Zigzag Graphene Nanoflake

Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...
