Extinction of ferromagnetism in highly ordered pyrolytic graphite by annealing
We report that the ferromagnetism of highly ordered pyrolytic graphite (HOPG) samples as measured by hysteretic magnetization loops can be diminished and eventually extinguished with sufficiently long high vacuum anneals at temperatures on the order of 2300 !C. Concomitant with the extinction of ferromagnetism, we observe an annealinduced increase in grain size (accompanied by possible edge rec...
متن کاملClean and highly ordered graphene synthesized in the gas phase.
We report that the substrate-free gas-phase graphene synthesis method produces clean and highly ordered graphene sheets that are similar in quality to the graphene obtained through the mechanical exfoliation of highly oriented pyrolytic graphite.
متن کاملLarge and flat graphene flakes produced by epoxy bonding and reverse exfoliation of highly oriented pyrolytic graphite.
We present a fabrication method producing large and flat graphene flakes that have a few layers down to a single layer based on substrate bonding of a thick sample of highly oriented pyrolytic graphite (HOPG), followed by its controlled exfoliation down to the few to single graphene atomic layers. As the graphite underlayer is intimately bonded to the substrate during the exfoliation process, t...
متن کاملNonlinear Optical Absorption of Carbon Nanostructures Synthesized by Laser Ablation of Highly Oriented Pyrolytic Graphite in Organic Solvents
In this study, Highly Oriented Pyrolytic Graphite was ablated in various polar and nonpolar solvents by Q-switched neodymium: yttrium-aluminum-garnet laser (wavelength=1064 nm, frequency=2 kHz, pulse duration=240 ns). Then, the products were examined using Scanning Electron Microscopy and UV-Vis spectroscopy. The images showed that different carbon structures such as cauliflower-like structures...
متن کاملExfoliation of graphene sheets via high energy wet milling of graphite in 2-ethylhexanol and kerosene
Graphene sheets have been exfoliated from bulk graphite using high energy wet milling in two different solvents that were 2-ethylhexanol and kerosene. The milling process was performed for 60 h using a planetary ball mill. Morphological characteristics were investigated using scanning electron microscope (SEM) and transmission electron microscope (TEM). On the other hand, the structural charact...
