摘要：

Closing individual, thin, multiwalled carbon nanotubes is performed in situ in a transmission electron microscope (see Figure). The closure of the initially open end of the nanotube results from the presence of a strong electric field and the accompanied electron emission. The closed-cap nanotubes exhibit high current stability, which is of advantage for their use as electron sources.
