Figure 2

(a–j) Extinction spectra (1−T/T0) for few-layer BP on quartz substrates with layer number N=2–9, 13 and 15. The labels E11, E22, E33 and E44 denote the first, second, third and fourth subband transitions, asterisks (*) denote hybrid transitions, respectively. (k) Extinction spectra for a thick bulk BP (thickness>100 nm) on intrinsic Si substrate. The black and red curves represent spectra for two different light polarizations.
