Weak surface electron-phonon coupling in the topological insulator Bi2Se3 nanoparticles revealed by electron spin resonance

초록

Hydrogen-doping of Bi2Se3 nanoparticles has provided a rare opportunity to study the surface state of a topological insulator by means of electron spin resonance (ESR) and static magnetization measurements. As a result, a weak surface electron-phonon coupling in the topological insulator Bi2Se3 nanoparticles was revealed by ESR signals that were attributed to the surface conduction electrons.
