摘要:

The dark‐field diffraction contrast of helical nanotubes (NTs) is shown to be asymmetric when an NT is tilted at appropriate angle with respect to the incident electron beam. This phenomenon was used for the chirality determination of multi‐shell NTs observed in MoS2layered compound. Both kinds of NT — helical and non‐helical — were found. In the case of helical NTs only right‐hand chirality w
