Abstract

Synthesis of single-crystal bismuth telluride nanorods is reported by using a low-temperature, template-free approach (see Figure). Films of thioglycolic acid functionalized nanorods doped with sulfur exhibit n-type behavior with a high Seebeck coefficient, holding promise for thermoelectric device applications.
