Anderson (1962) proposed that the conduction band offset at A/B interface is given by the electron affinity difference between A and B materials as ΔEc = χB − χA. Using the observed band-gap energies, one
where:α,λandEare absorption coefficient, wavelength and photon energy, respectively;biandEg,i(bandgap) are parametric constants;n0andcjare parametric constants of Cauchy empirical formula; the exponentm(i) has two possible values of 2 and 1/2 for indirect (Tauc) and direct bandgap absorption, ...
Using the following formula [3], the specific capacitance (Csp) of EDLC cells was determined. 𝐶𝑠𝑝=12𝑚𝑣(𝑉𝑓−𝑉𝑖) ∫𝑉𝑓𝑉𝑖𝐼 (𝑉)𝑑𝑉Csp=12mvVf−Vi ∫ViVfI VdV (1) where I(V)dV represents the CV’s area as calculated by the OriginPro ...
