内容記述 | A model for electron field emission from carbon nanotubes (CNTs) has been developed and modeling results are presented. The model assumes that for high emission currents, part of the electrons behave as quasifree. As a result, the spatial confinement quantization of their states appears, the tunneling field emission taking place from these states into the vacuum. The probability of finding an electron in a small axial interval is higher close to the CNT cylindrical body, while the extraction field is higher on the CNT hemispherical tip. These two opposite trends lead to enhancement of the CNT lateral field emission for higher extraction voltages. The model outlines the possibility of inhomogeneous electron field emission for very thin CNTs at high emission levels and the appearance of peculiar ring-shaped and/or spot-shaped field emission images, in accordance to available experimental observations. | |||||
