Description:
Author(s): Wee Kiang Chong, Guichuan Xing, Yun Liu, Ee Ling Gui, Qing Zhang, Qihua Xiong, Nripan Mathews, Chee Kwan Gan, and Tze Chien Sum We report observations of coherent phonon oscillations in solution-processed polycrystalline stibnite (Sb2S3) photovoltaic thin films using transient absorption spectroscopy. Detailed optical spectroscopy correlated by extensive first-principles lattice dynamics calculations indicates that the coher... [Phys. Rev. B 90, 035208] Published Wed Jul 23, 2014
