Staying single : Individual, ultralong, single‐crystalline Te nanotubes become unintentionally doped when synthesized by a chemical method. They show metallic character in the wide temperature rangeof 5–300 K (see graph), which issupported by first‐principles density functional theory calculations. Nanodevicesare fabricated based on a single Tenanotube by using a focused‐ion‐beamdeposition technique.
