Abstract

In this work, the static electronic (hyper)polarizabilities of (0, n) and (n, 0) lepidocrocite nanotubes have been computed for the first time using the coupled perturbed Kohn Sham (CPKS) scheme recently implemented in the CRYSTAL code. The dependence of the response properties of the 1D-systems to electric field on the choice of the basis set and density functional has been critically analyzed. Results obtained by fit at the infinite diameter limit are compared to those of the lepidocrocite flat sheet.
