Comprehensive calculations of the Rh decoration effect on zigzag CNTs with n ranging from 7 to 12 were conducted in this work to understand the effect of Rh doping on geometric structures and electronic behaviors upon metallic and semiconducting CNTs. The obtained results indicated that Rh dopant not only contributes to the deformation of C-C bonds on the sidewall of CNTs, but also transforms the electron distribution of related complexes, thereby leading to a remarkable increase of the conductivity of pure CNTs given the emerged novel state within the energy gap for metallic CNTs and the narrowed energy gap for semiconducting CNTs. Our calculations will be meaningful for exploiting novel CNT-based materials with better sensitivity to electrons and higher electrical conductivity compared with pure CNTs.

The luxury market keeps growing in the global world. Marketing scholars focus on Chinese luxury consumers, because Chinese consumers show different characteristics comparing to foreign consumers. Personal hedonic value cannot be ignored among factors which influence consumers’ purchase intention. After the survey on 128 consumers who have luxury purchasing experience, the study finds out that as the two of three sub-dimensions of hedonic value, self-gifting and self-pleasure can significantly influence luxury perceived value, but self-enrichment has nothing to do with it. Luxury perceived value can directly affect consumers’ purchase intention on luxury products. But this relationship can be negatively moderated by interpersonal effects. At the end, managerial implications and theoretical contributions are discussed.
