Valley-selective optical Stark effect probed by Kerr rotation
Trevor LaMountain, Hadallia Bergeron, Itamar Balla +3
The ability to monitor and control distinct states is at the heart of emerging quantum technologies. The valley pseudospin in transition metal dichalcogenide (TMDC) monolayers is a…
Correlated In-Situ Low-Frequency Noise and Impedance Spectroscopy Reveal Recombination Dynamics in Organic Solar Cells using Fullerene and Non-Fullerene Acceptors
Kyle A. Luck, Vinod K. Sangwan, Patrick E. Hartnett +4
Non-fullerene acceptors based on perylenediimides (PDIs) have garnered significant interest as an alternative to fullerene acceptors in organic photovoltaics (OPVs), but their char…
Ultrafast Exciton Dissociation and Long-Lived Charge Separation in a Photovoltaic Pentacene MoS2 van der Waals Heterojunction
Stephanie Bettis Homan, Vinod K. Sangwan, Itamar Balla +3
Van der Waals heterojunctions between two-dimensional (2D) layered materials and nanomaterials of different dimensions present unique opportunities for gate-tunable optoelectronic…
Control of interlayer delocalization in 2H transition metal dichalcogenides
Kuang-Chung Wang, Teodor K. Stanev, Daniel Valencia +14
It is assessed in detail both experimentally and theoretically how the interlayer coupling of transition metal dichalcogenides controls the electronic properties of the respective…
