Ultrafast spectroscopy for materials science – and an experience as a female scientist in Japan
Opto-electronic devices, such as photocatalysts, photovoltatics, light emitting diodes and lasers convert light into electric current or vice versa in metals and semiconductors. The opto-electronic conversion processes occur typically on time scales ranging from femtosecond (10^-15 s) to nanoseconds (10^-9 s), and are often affected by collective atomic vibrations or phonons. In the present seminar I will introduce fundamental studies on ultrafast carrier and phonon dynamics at semiconductor interfaces in lead halide perovskite solar cells and lattice-matched GaP/Si(001). I will also talk about my personal experiences of being one of the few female physicists in Japan.
