Proper ab-initio dielectric function of 2D materials and their polarizable thickness
Lorenzo Sponza, François Ducastelle
In this paper we derive a formalism allowing us to separate inter-layer contributions to the polarizability of a periodic array of 2D materials from intra-layer ones. To this aim,…
Excitons in bulk black phosphorus evidenced by photoluminescence at low temperature
Etienne Carré, Lorenzo Sponza, Alain Lusson +4
Atomic layers of Black Phosphorus (BP) present unique opto-electronic properties dominated by a direct tunable bandgap in a wide spectral range from visible to mid-infrared. In thi…
The impact of stress on the electronic structure of phosphorus allotropes stacked on hexagonal boron nitride
Baptiste Bienvenu, Hakim Amara, François Ducastelle +1
We study the mechanical and electronic properties of heterobilayers composed of black phosphorus (BP) on hexagonal boron nitride (hBN) and of blue phosphorus (\Pblue) on hBN by mea…
