碳纳米片场发射电子的能量分布:量子尺寸效应的表现

Energy distributions of field emitted electrons from carbon nanosheets: manifestation of the quantum size effect

V. L. Katkov, V. A. Osipov

摘要:

我们强调的重要性,实验与电压依赖的场发射能量分布分析的碳纳米片。我们的分析表明,能带结构的场发射电子的能量分布在少层石墨烯的关键影响。除了主峰,我们发现特征的子峰的能量分布。它们的位置强烈地依赖于层的数量和层间相互作用。在碳纳米片的场致发射实验中发现这些峰将清楚地表明这些新材料中的量子尺寸效应。

英文摘要:

We emphasize the importance of experiments with voltage dependent field emission energy distribution analysis in carbon nanosheets. Our analysis shows the crucial influence of the band structure on the energy distribution of field emitted electrons in few-layer graphene. In addition to the main peak we found characteristic sub-peaks in the energy distribution. Their positions strongly depend on the number of layers and the inter-layer interaction. The discovery of these peaks in field emission experiments from carbon nanosheets would be a clear manifestation of the quantum size effect in these new materials.
