We report mass and conductance adsorption isotherms of Kr on individual, single-walled, suspended carbon nanotubes for 53?K<T<90?K for several devices, and of 4He for 5?K<T<8?K for two devices. Different nanotubes, probably of different diameter and/or chirality, yield different phase diagrams, full monolayer coverages, and partial wetting characteristics for Kr. The 4He results show, for one of the devices, a greatly reduced heat of adsorption as compared to the well studied system of 4He on graphite.
