Electrical monitoring of organic crystal phase transition using MoS2 field effect transistor


Electrical monitoring of organic crystal phase transition using MoS2 field effect transistor

Hybrid van der Waals heterostructures made of 2D materials and organic molecules exploit the high sensitivity of 2D materials to all interfacial modifications and the inherent versatility of the organic compounds. In this study, we are interested in the quinoidal zwitterion/MoS2 hybrid system in which organic crystals are grown by epitaxy on the MoS2 surface… Read More

Luminescence in hexagonal boron nitride single layer: exciton-phonon coupling and the role of substrate


Luminescence in hexagonal boron nitride single layer: exciton-phonon coupling and the role of substrate

In this new work we study luminescence in monolayer hexagonal boron nitride (m-hBN) using a new ab-initio approach that takes into account the effects of atomic vibrations on the luminescence spectra. We construct the dynamical exciton-phonon self-energy, then use it to perturbatively correct the optical response functions and test this approach on bulk hBN as… Read More
