Abstract
ITO whiskers were grown by VLS mechanism along a glass substrate at t<30s, The whiskers grew perpendicular to the substrate at t>30s. They have a Sn-rich droplet on the tip. As the whiskers incorporated Sn on the substrate at t>30s, they grew along the substrate. When the Sn on the substrate was decreased with deposition time, the whiskers incorporated molecules directly from the vapor phase and grew perpendicularly.
