Abstract
Strong size dependent structures of Si nanowires, grown via indium nanoparticles, have been revealed by high-resolution transmission electron microscopy studies. It is found that, below the critical value of particle diameter of similar to 100 nm, the growth changes from <111 > to predominantly <211 > direction and the formation of multiple {111} twins changes from perpendicular to the <111 > growth direction to parallel to the <211 > axial direction. The growth mechanisms are discussed in terms of relative surface/interface energy, using Au catalyzed Si nanowires as a comparative benchmark.
