Revealing the Substrate Dependent Ultrafast Phonon Dynamics in Bi2Se3 Thin Films
Abstract The bulk carrier excitation influences the phonon dynamics, which can alter and modulate the surface charge density of topological insulators such as bismuth selenide (Bi2Se3). This work investigates the charge carrier and phonon dynamics in Bi2Se3 grown on various substrates. The orientati...
