摘要	We report a method of controlling field-emission patterns from an isolated single-walled carbon nanotube (SWCNT) rope. By positioning two soda-lime glass flakes on both sides of a SWCNT rope, we found an anomalous current jump, enlarging the field emission current above the threshold bias voltage. The electron trajectories were systematically controlled with different configurations of glass flakes. This was explained by the induced charges on the surface of the dielectric that modified the electric field distribution near the cathode and anode, and hence, the electron trajectories and the field emission patterns as well. This opens a possibility of tuning electron beam trajectories in field emission that can be applied to various electron sources such as field emission displays and cold cathode lamps.
