We develop a simple scaling relationship between the exciton binding energy and the external dielectric function and thus quantify the effect of screening. Our results imply that the underlying particle interaction energies change by hundreds of meV.p. 1485 - 1488Science & technologyPhysical sciencesTechnologyChemistry, multidisciplinaryChemistry, physicalNanoscience & nanotechnologyPhysics, appliedPhysics, condensed matterChemistryMaterials sciencePhysicsRaman scatteringSommerfeld factorsComputer simulationEnergy transferModels, chemicalNanotubes, carbonSpectrum analysis, RamanNanoscience & nanotechnologyArticle10.1021/nl070193p0000-0002-8594-892X (Unlu, MS)0000-0002-3978-7993 (Swan, AK)48108
