WebApr 12, 2024 · The spectral transmission, reflection, and absorption profiles of ITO/Si PhCs (3 μm lattice constant) are shown in Fig. 5D. High absorption on average of more than ~90% from 300 to 1000 nm is observed. An n-Si wafer with 3000 ohm·cm resistivity is used to configure the device, the EQE of which is measured in Fig. 5E. WebUsing the Boltzmann constant, the formula to derive the constant is expressed as the following: σ = (2 x π 5 x k B4) / (15 x h 3 x c 2) = 5.670367 x 10 -8 W / (m 2 x K 4) Here: k B = Boltzmann constant = 1.380649 x 10 -23 joules per K (J x K -1 ); h = Planck's constant = 6.62607015 x 10 -34 joule-seconds (J x s); and
