摘要: Abstract We determined the optical constants below absorption edge of amorphous films Si 1− x Au ( between 0.07 and 0.30) prepared by getter sputtering in argon. In range 0.15 to 0.5 eV we found that increased with increasing content could be described Mott's formula for a.c. conductivity σ(ω) ≈ ω 2 [In I 0 /ω)] 4 ≃ 4.5 at = 0.11 3.8 0.29; 10–100 K it changed only slightly temperature. The is interpreted as due direct transitions involving atoms.
