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…
Temperature- and charge carrier density-dependent electronic response in methylammonium lead iodide
Jiacheng Wang Jungmin Park, Lei Gao, Lucia Di Virgilio +8
Understanding carrier dynamics in photoexcited metal-halide perovskites is key for optoelectronic devices such as solar cells (low carrier densities) and lasers (high carrier densi…
Cove-edged Chiral Graphene Nanoribbons with Chirality-Dependent Bandgap and Carrier Mobility
K. Liu, W. Zheng, S. Osella +13
Graphene nanoribbons (GNRs) have garnered significant interest due to their highly customizable physicochemical properties and potential utility in nanoelectronics. Besides control…
Beyond the band edge: Unveiling high-mobility hot carriers in a two-dimensional conjugated coordination polymer
Shuai Fu, Xing Huang, Guoquan Gao +19
Hot carriers, inheriting excess kinetic energy from high-energy photons, underpin numerous optoelectronic applications involving non-equilibrium transport processes. Current resear…
