Excitons in few-layer hexagonal boron nitride: Davydov splitting and surface localization
Fulvio Paleari, Thomas Galvani, Hakim Amara +3
Hexagonal boron nitride (hBN) has been attracting great attention because of its strong excitonic effects. Taking into account few-layer systems, we investigate theoretically the e…
Entropy driven stability of chiral single-walled carbon nanotubes
Yann Magnin, Hakim Amara, François Ducastelle +2
Single-walled carbon nanotubes are hollow cylinders, that can grow centimeters long by carbon incorporation at the interface with a catalyst. They display semi-conducting or metall…
Bright luminescence from indirect and strongly bound excitons in hBN
Leonard Schue, Lorenzo Sponza, Alexandre Plaud +6
A quantitative analysis of the excitonic luminescence efficiency in hexagonal boron nitride (hBN) is carried out by cathodoluminescence in the ultraviolet range and compared with z…
