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…
