Quasiparticle phono-conversion: filming carriers coalescing into excitons
Enrico Perfetto, Takumi Fukuda, Xing Zhu +12
Condensed matter physics is replete with phenomena involving high-energy free particles coalescing into low-energy bound few-particle states. While the cooling of the individual pa…
Driving non-trivial quantum phases in conventional semiconductors with intense excitonic fields
Vivek Pareek, David R. Bacon, Xing Zhu +12
Inducing novel quantum phases and topologies in materials using intense light fields is a key objective of modern condensed matter physics, but nonetheless faces significant experi…
Moiré-localized interlayer exciton wavefunctions captured by imaging its electron and hole constituents
Ouri Karni, Elyse Barré, Vivek Pareek +21
Interlayer excitons (ILXs) - electron-hole pairs bound across two atomically thin layered semiconductors - have emerged as attractive platforms to study exciton condensation, singl…
Unraveling the varied nature and roles of defects in hybrid halide perovskites with time-resolved photoemission electron microscopy
Sofiia Kosar, Andrew J. Winchester, Tiarnan A. S. Doherty +9
With rapidly growing photoconversion efficiencies, hybrid perovskite solar cells have emerged as promising contenders for next generation, low-cost photovoltaic technologies. Yet,…
Experimental measurement of the intrinsic excitonic wavefunction
Michael K. L. Man, Julien Madéo, Chakradhar Sahoo +15
An exciton, a two-body composite quasiparticle formed of an electron and hole, is a fundamental optical excitation in condensed-matter systems. Since its discovery nearly a century…
Directly visualizing the momentum forbidden dark excitons and their dynamics in atomically thin semiconductors
Julien Madéo, Michael K. L. Man, Chakradhar Sahoo +11
Resolving the momentum degree of freedom of excitons - electron-hole pairs bound by the Coulomb attraction in a photoexcited semiconductor, has remained a largely elusive goal for…
