Using a sample holder with an integrated force sensor, a collection of carbon nanotubesfilled with Ga-doped ZnS, and spanning a broad window of lengths and diameters, has beenmechanically studied inside a transmission electron microscope. The successful evaluationof the filled nanostructures was seen to depend on their slenderness ratio. Upon controlledremoval of the encapsulated sulfide, the system considerably changed its response touniaxial compressive stress. This report follows part 1 of the study which wasinstrument-focused and laid the ground to achieve consistent results with a noveltype of nanomechanics setup for one-dimensional nanostructures (Costa et al 2009Nanotechnology 40 405706).
