Mid-infrared polarized emission from black phosphorus light-emitting diodes
Junjia Wang, Adrien Rousseau, Mei Yang +3
The mid-infrared (MIR) spectral range is of immense use for civilian and military applications. The large number of vibrational absorption bands in this range can be used for gas s…
Spectral responsivity and photoconductive gain in thin film black phosphorus photodetectors
Junjia Wang, Adrien Rousseau, Elad Eizner +4
We have fabricated black phosphorus photodetectors and characterized their full spectral responsivity. These devices, which are effectively in the bulk thin film limit, show broadb…
Time-resolved imaging of non-diffusive carrier transport in long-lifetime halide perovskite thin films
Aravindan Sridharan, Nakita K. Noel, Hyeon Hwang +3
Owing to their exceptional semiconducting properties, hybrid inorganic-organic perovskites show great promise as photovoltaic absorbers. In these materials, long-range diffusion of…
Triplet harvesting in the polaritonic regime: a variational polaron approach
Luis A. Martínez-Martínez, Elad Eizner, Stéphane Kéna-Cohen +1
We explore the electroluminescence efficiency for a quantum mechanical model of a large number of molecular emitters embedded in an optical microcavity. We characterize the circums…
Inverting Singlet and Triplet Excited States using Strong Light-Matter Coupling
Elad Eizner, Luis A. Martínez-Martínez, Joel Yuen-Zhou +1
In organic microcavities, hybrid light-matter states can form with energies that differ from the bare molecular excitation energies by nearly 1 eV. A timely question, given recent…
