Laura Maria HerzFInstP is a Professor of Physics at the University of Oxford. She works on femtosecond spectroscopy for the analysis of semiconductor materials.[1]
Herz is an expert in perovskite semiconductors.[7] She has researched the origins of the high charge-carrier mobilities in perovskite materials.[8] She demonstrated that their high efficiency in solar cells was due to long charge-carrier diffusion lengths and non-Langevin recombination.[9][10] She identified that perovskite light emission is broad and can be used in Ultrafast lasers.[11] She recognised that the origin of this broadening is Fröhlich coupling to longitudinal optical phonons.[12]
Herz is also interested in self-assembly and nanoscale effects.[13] She works on Biomimetics light harvesting structures made of porphyrin nanorings[14][15] to explore delocalised excited states.[16][17] She is the co-director of the Imperial College London Centre for Doctoral Training in Plastic Electronic Materials.[2]
She appeared on the BBC Radio 4 show In Our Time in 2015.[18] She will join University of Bayreuth in 2018 to deliver a series of lectures.[19]
