Toward a novel and accurate relationship between electrical and optical conductivity in opto-material sciences: New strategy

Optimizing the structure and optoelectronic properties of cuprite thin films via a plasma focus device as a solar cell absorber layer

“…The value of σ opt is contingent upon both ε r and ε i , providing insights into the density of electronic states within the material's bandgap. σ opt is correlated with n and α through the following relationship: 80 while σ elec is obtained from the relation: 81,82 The changes in σ opt and σ elec concerning photon energy are depicted in Fig. 11(a and b).…”

Correction: Influence of time dependent laser-irradiation for tuning the linear–nonlinear optical response of quaternary Ag10In15S15Se60 films for optoelectronic applications

“…Gomma et al have recently reported the formula for the calculation of electrical conductivity as follows, 1 where ‘ n ’ is the refractive index and ‘ k ’ is the extinction coefficient. The conductance of charge carriers because of optical excitation is represented by the σ opt .…”
