WebWe note that, in the case of Zn 2 (TTFTB), the computed electronic band gap and the optical band gap from a Tauc plot (2.0 eV) are in reasonable agreement. (96) However, in the absence of transport measurements, optical band gaps alone are not sufficient to determine that a compound is a semiconductor. WebThe energy gap between the highest occupied and lowest unoccupied electronic levels is a critical parameter determining the electronic, optical, redox, and transport (electrical) properties of a material. However, the energy gap comes in many flavors, such as the band gap, HOMO–LUMO gap, fundamental gap, optical gap, or transport gap, with ... ctr with cbc-mac protocol
