Electrical conductivity of quasi-2D foams
Quasi-2D foams consist of monolayers of bubbles squeezed between two narrowly spaced plates. These simplified foams have served successfully in the past to shed light on numerous issues in foam physics. Here we consider the electrical conductivity of such model foams. We compare experiments to a model which we propose, and which successfully relates the structural and the conductive properties ...
متن کاملConductivity of defectless graphene
Conductivity of graphene, a flat monolayer of carbon atoms, as a function of doping charge shows a pronounced minimum at the neutrality, compensation point. The theory predicts for this point a universal conductivity, whereas the experimental conductivity exceeds this prediction by few times. This discrepancy persists for long time now and may justify an additional study of zero gap semiconduct...
متن کاملThermal conductivity of graphene laminate.
We have investigated thermal conductivity of graphene laminate films deposited on polyethylene terephthalate substrates. Two types of graphene laminate were studied, as deposited and compressed, in order to determine the physical parameters affecting the heat conduction the most. The measurements were performed using the optothermal Raman technique and a set of suspended samples with the graphe...
متن کاملAdsorbate-limited conductivity of graphene.
We present a theory of electronic transport in graphene in the presence of randomly placed adsorbates. Our analysis predicts a marked asymmetry of the conductivity about the Dirac point, as well as a negative weak-localization magnetoresistivity. In the region of strong scattering, renormalization group corrections drive the system further towards insulating behavior. These results explain key ...
متن کاملThermal Conductivity and Thermal Contact Resistance of Metal Foams
Unique specifications of metal foams such as relatively low cost, ultra-low density, high surface-area-to-volume ratio, and most importantly, the ability to mix the passing fluid provide them a great potential for a variety of thermal-fluidics
