Zeeman spectroscopy of the Be acceptor in GaAs to intermediate fields
Magneto-spectroscopy to 17.5 T of the Be acceptor impurity in GaAs in the Faraday configuration using unpolarised radiation is reported. One strong component of the G-line is observed. This moves slowly with field at ~0.24cm-1/T. All eight transitions expected for the D-line are observed, allowing some of the splittings of the field-induced components of the ground and the second excited states to be determined.
