WebFeb 21, 2024 · Using Tauc relation, (αhν) n =(Ahν-E g) the optical energy band gap ... In the Tauc diagram, (αhν) n is plotted versus hν, by which the energy band gap can be extrapolated using the straight-line part of the curves. We plotted the WS 2 nanosheet’s curves for n = 2 and also for n = 0.5. WebThe band gap is called "direct" if the crystal momentum of electrons and holes is the same in both the conduction band and the valence band; an electron can directly emit a photon. In an "indirect" gap, a photon cannot be emitted because the electron must pass through an intermediate state and transfer momentum to the crystal lattice.
