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…
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,…
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…
Similar ultrafast dynamics of several dissimilar Dirac and Weyl semimetals
Chris P. Weber, Bryan S. Berggren, Madison G. Masten +13
Recent years have seen the rapid discovery of solids whose low-energy electrons have a massless, linear dispersion, such as Weyl, line-node, and Dirac semimetals. The remarkable op…
Chemical Vapor Deposition Synthesized Atomically Thin Molybdenum Disulfide with Optoelectronic-Grade Crystalline Quality
Ismail Bilgin, Fangze Liu, Anthony Vargas +8
The ability to synthesize high-quality samples over large areas and at low cost is one of the biggest challenges during the developmental stage of any novel material. While chemica…
