These patterns allow us to demonstrate how key principles governing crystallization have to be adapted in order to accomplish solidification in restricted geometries. 4He, Ar, and the spherical close packed phases of CO and N2 adjust to the pore geometry by introducing a sizeable amount of stacking faults. For the pore solidified, medium-length chain-like n-C19H40 we observe a close packed structure without lamellar ordering, whereas for the short-chain C 9H20 the layering principle survives, albeit in a modified fashion compared to the bulk phase.enPhysikConference Paper10.1557/proc-876-r3.1Other
