Abstract

Using density functional theory we have calculated work function and Young's modulus of various platinum nanotubes. On the average, work functions of achiral platinum nanotubes increase with increasing diameter and those of chiral nanotubes are found to increase with increasing chirality. This study also finds that Young's modulus of single wall platinum nanotubes increase with increasing diameter and approaches a saturation value in the higher diameter region. Reasons behind such observations are explained.
