A hidden bulk polymorph governs charge transport dimensionality in an organic semiconductor
Caterina Zuffa, Marco Bardini, Fabian Gasser +11
Organic semiconductors (OSCs) are widely explored for flexible optoelectronic technologies, with performance governed not only by molecular design, but also by solid-state packing,…

Observation of a phonon bottleneck effect on the thermal depopulation from a photoexcited shallow defect in silicon
Sergio Revuelta, Hai I. Wang, Mischa Bonn +1
We report the observation of a phonon bottleneck effect impacting the thermal depopulation of photoexcited shallow defects in high-resistivity silicon. Using time-resolved terahert…
