Abstract
Transparent conducting oxides (TCOs) are semiconductors gaind much interest due to applications in optoelectronic and tranport properties. Herein, we investigated optoelectronic and tranport properties of Rh doped Fe3BO6 compound. The band structure of parent compound for spin up shows insulating nature while other channel is semiconducting nature (4.181 eV Up/2.41 eV Dn).When spinel material doped with Rh3+, the band gap is reduced for both spin channels (2.59 eV (Up)/ 0.59 (Dn), respectively. The optical dispersion exhibits strong absorption in the UV region, for both materials. Reflectivity spectra, for both materials visible-UV indicating good coating materials to reduce solar heating. The transport parameters are computed. It's observed that large ZT value Fe3BO6 made this compoud most promisining in thermoelectric applications. The effective masses of species were also analyzed by curve fitting method, results showed that nature of band at 0.69 is changed from direct to indirect for doped compound.
