摘要：

Spectral measurements in the frequency range from 10 to 130 cm-1 in magnetic fields from 0 to 30 kG of the far infrared photoconductivity due to shallow donors in GaAs are reported. The measurements reveal peaks due to the isolated (1s→ 2p) and (1s→ 3p) transitions in addition to a broad continuum at higher energy. From the energy of these peak transitions and their splitting in a magnetic field we obtain a donor ionization energy of 5.86 ± 0.02 meV and an effective mass of0.0665 ± .0005 m0. © 1969.
