Ahumada-lazo, R, Alanis, J A, Parkinson, P, Binks, D J, Hardman, S J O, Griffiths, J T, Wisnivesky Rocca Rivarola, F, Humphreys, C J, Ducati, C & Davis, N J L K 2019, ' Emission Properties and Ultrafast Carrier Dynamics of CsPbCl3 Perovskite Nanocrystals ', The Journal of Physical Chemistry C . https://doi.org/10.1021/acs.jpcc.8b11906
Fluence-dependent photoluminescence and ultrafast transient absorption spectroscopy are used to study the dynamic behavior of carriers in CsPbCl3 perovskite nanocrystals. At low excitation fluences, the radiative recombination rate is outcompeted by

We report on a comparative study of the low temperature emission and polarisation properties of InGaN/GaN quantum wells grown on nonpolar ($ 11\bar{2}0 $) a-plane and ($ 10\bar{1}0 $) m-plane free-standing bulk GaN substrates where the In content var

AC photoelectrochemical imaging at electrolyte−semiconductor interfaces provides spatially resolved information such as surface potentials, ion concentrations and electrical impedance. In this work, thin films of InGaN/GaN were used successfully fo

This paper describes a detailed analysis of the effects of high temperatures on the optical performance and structural characteristics of GaN-based LED structures with a high threading dislocation density. Results show that, as a consequence of stora

Astronomical calculations have been used to reconstruct the Jewish calendar in the first century AD and to date a lunar eclipse that biblical and other references suggest followed the Crucifixion. The evidence points to Friday 3 April AD 33 as the da
