Abstract
Tellurium particles produced by evaporation in argon at a pressure of several Torr are observed to occur with two distinct shapes. They are either spherical or egg-shaped or else they are rod-shaped. The rods are hexagonal in cross section, bounded by {10.0} planes and have their axes parallel to the [00.1] direction. Both kinds of particle are single crystals with the normal hexagonal structure of α-tellurium. They nucleate and grow in different zones of the tellurium smoke. The fact that particles grown in different zones have different shapes is explained in terms of the temperature dependence of the spatial anisotropy of the γ-plot where γ is the specific surface free energy.
