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…
