Laser Post-Processing of Halide Perovskites for Enhanced Photoluminescence and Absorbance
(IOP Publishing Ltd, 2018-11-05)
Hybrid halide perovskites have emerged as one of the most promising type of materials for thin-film photovoltaic and light-emitting devices. Further boosting their performance is critically important for commercialization. ...
Ultrafast Dynamics of Quasiparticles and Coherent Acoustic Phonons in Slightly Underdoped (BaK)Fe₂As₂
(Nature Publishing Group, 2016-05-16)
We have utilized ultrafast optical spectroscopy to study carrier dynamics in slightly underdoped (BaK)Fe2As2 crystals without magnetic transition. The photoelastic signals due to coherent acoustic phonons have been ...
