Abstract
An ion source(s) is configured to generate ions from one or more elements including a plurality of different isotopes or unique molecular combinations of two or more different isotopes from at least one of the selected elements. A selection filter(s) directs a subset of the ions onto a catalytic transmembrane to grow nanotubes of a specific isotope composition on the opposite side of the transmembrane. The nanotubes may be uniformly or selectively doped with dopant atoms. A controller can configure the selection filter(s) to sequentially pass different subsets of ions to form isotope, molecular or element junctions in the growing nanotubes.
