Spectroscopic size and thickness metrics for liquid-exfoliated h-BN
Aideen Griffin, Andrew Harvey, Brian Cunningham +8
For many 2D materials, optical and Raman spectra are richly structured, and convey information on a range of parameters including nanosheet size and defect content. By contrast, th…

Accurate optical properties from first principles: a Quasiparticle Self consistent GW plus Bethe-Salpeter Equation approach
Brian Cunningham, Pooya Azarhoosh, Dimitar Pashov +2
We present an approach to calculate the optical absorption spectra that combines the quasiparticle self-consistent GW method [Phys. Rev. B, 76 165106 (2007)] for the electronic str…
