We have investigated the effect of FeSi 2 source purity on the electrical property of β-FeSi 2 grown from solution. A high-purity FeSi 2 source avoided a contamination of Cu and W metals was synthesized by melting a high-purity Fe (5N) and Si (5N-up

We have grown Mg 2 Si bulk crystals by the vertical Bridgman method using a high-purity Mg (6N-up) source. The grown crystals were single-phase Mg 2 Si and had well-developed grains (1–5 mm 3 ). Laue observations and SEM-EDX observations confirmed

Polarized optical reflectance of single crystalline β-FeSi2 has been investigated up to 3.1 eV for the light polarization of E//a, E//b and E//c. We observed the clear anisotropy in the spectrums of reflectance, refractive index n, extinction coeffi

The structural properties of β- and α-FeSi2 were examined by high-pressure x-ray diffraction at room temperature. In β-FeSi2, the lattice compression in the longest a axis is larger than in the b and c axes. The expected pressure-induced quenching
