Electron and hole doping of monolayer WSe2 induced by twisted ferroelectric hexagonal boron nitride
Jules Fraunié, Rayan Jamil, Richard Kantelberg +12
For the past few years, 2D ferroelectric materials have attracted strong interest for their potential in future nanoelectronics devices. The recent discovery of 2D ferroelectricity…
Non-linear diffusion of negatively charged excitons in WSe2 monolayer
D. Beret, L. Ren, C. Robert +10
We investigate the diffusion process of negatively charged excitons (trions) in WSe2 transition metal dichalcogenide monolayer. We measure time-resolved photoluminescence spatial p…
Exciton spectroscopy and diffusion in MoSe2-WSe2 lateral heterostructures encapsulated in hexagonal boron nitride
Dorian Beret, Ioannis Paradisanos, Ziyang Gan +17
Chemical vapor deposition (CVD) allows lateral edge epitaxy of transition metal dichalcogenide heterostructures with potential applications in optoelectronics. Critical for carrier…
Relaxation and darkening of excitonic complexes in electrostatically-doped monolayer semiconductors: Roles of exciton-electron and trion-electron interactions
Min Yang, Lei Ren, Cedric Robert +5
We present photoluminescence measurements in monolayer WSe, which point to the importance of the interaction between charged particles and excitonic complexes. The theoretical…
Imaging Seebeck drift of excitons and trions in MoSe2 monolayers
Sangjun Park, Bo Han, Caroline Boule +10
Hyperspectral imaging at cryogenic temperatures is used to investigate exciton and trion propagation in MoSe monolayers encapsulated with hexagonal boron nitride (hBN). Under a…
Interlayer exciton mediated second harmonic generation in bilayer MoS2
Shivangi Shree, Delphine Lagarde, Laurent Lombez +10
Second harmonic generation (SHG) is a non-linear optical process, where two photons coherently combine into one photon of twice their energy. Efficient SHG occurs for crystals with…
