Ultrafast Dynamics of the Charge Density Wave State in Layered CuxTiSe2
D. B. Lioi, R. D. Schaller, G. P. Wiederrecht +1
We report on a transient optical reflectivity study of the charge density wave (CDW) in CuxTiSe2 single crystals. Our measurements reveal that the system undergoes a quantum phase…
Vacancy Relaxation in Cuprous Oxide (CuO)
Laszlo Frazer, Kelvin B. Chang, Richard D. Schaller +2
Phonons are produced when an excited vacancy in cuprous oxide (CuO) relaxes. Time resolved luminescence was used to find the excited copper vacancy (acceptor) and oxygen vacanc…
Simultaneous band gap narrowing and carrier lifetime prolongation of organic-inorganic trihalide perovskites
Lingping Kong, Gang Liu, Jue Gong +12
The organic-inorganic hybrid lead trihalide perovskites have been emerging as the most attractive photovoltaic material. As regulated by Shockley-Queisser theory, a formidable mate…
