Abstract

Plate-type ${\beta}-FeSi_2$ single crystals were grown using $FeSi_2$, Fe, and Si as starting materials by the chemical transport reaction method. The ${\beta}-FeSi_2$ single crystal was an orthorhombic structure. The direct optical energy gap was found to be 0.87eV at 300K. Hall effect shows a n-type conductivity in the ${\beta}-FeSi_2$ single crystal. The electrical resistivity values was 1.608$\Omega$cm and electron mobility was $3{\times}10^{-1}cm^2/V{\cdot}sec$ at room temperature.
