The field emission properties of the individual CNTs, where (a) I-E curve image from the individual CNT tips and (b) enlarged part indicated by red rectangle. (c) SEM image of the curved CNTs sidewall emitter with a diameter of 33 nm, (d) SEM image of a new emitter formed two CNTs, (e) the I-E curve during the above process occurred. (f,g) SEM images showing continued testing of the new emitter before and after the breakdown event, (h) the corresponding I-E curve recorded during the test process.
