Measurements are made of the photoelectromagnetic effect and photoconductivity in n- and p-type Ge doped with Au and Mn in the temperature range ∽ 330–90°K. The Au capture coefficients at 300°K are found to be: α0n = 5 × 10−10, α−n = 2 × 10−9, α = p = 1 × 10 −7 ( cm 3 sec ) ; while for Mn one obtains: α0n = 2 × 10−9, α−n = 4 × 10−10, α= = 6 × 10−10 (cm3/sec). The α= temperature dependence is of the form T−n, where n = 3.5 for Au and 4.5 for Mn. α0n and αn for Mn, as well as α0n for Au, are but weakly temperature dependent. The α-values obtained are in agreement with the analyses of the trapping phenomena in n-type samples. The experimental results are discussed and compared with the data given by other authors. |
