Exciton control inaroom temperature bulk semiconductor withcoherent strain pulses
(American Association for the Advancement of Science, 2019-11)
Controlling the excitonic optical properties of room temperature semiconductors using time-dependent perturbations is key to future optoelectronic applications. The optical Stark effect in bulk and low-dimensional materials ...
Giant Exciton Mott Density in Anatase TiO2
(American Physical Society, 2020-09-10)
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semiconductors. However, there is a lack of ...
Electron-phonon-driven three-dimensional metallicity in an insulating cuprate
(National Academy of Sciences, 2020-03-24)
The role of the crystal lattice for the electronic properties of cuprates and other high-temperature superconductors remains controversial despite decades of theoretical and experimental efforts. While the paradigm of ...
