Figure 4From: Tailoring of Seebeck coefficient with surface roughness effects in silicon sub-50-nm filmsEnergy resolved transmission spectra at zero applied voltage. For (a) A0 = 0.5 nm &λ's = 2.5 nm, 3.3 nm, 5 nm and for (b) λ = 2.5 nm &A0's = 0.1 nm, 0.3 nm, 0.5 nm. Temperature gradient ΔT = 20 K for both (a, b).Back to article page
