Structural, Electrical, and Photoconductive Properties of Individual Single‐Crystalline Tellurium Nanotubes Synthesized by a Chemical Route: Doping Effects on Electrical Structure

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.
