摘要：

Measurements of the Charge Collection Efficiency (CCE) of radiation detectors fabricated from semi-insulating GaAs wafers which have different thermal histories have been undertaken. A correlation between charge collection efficiency and electrical resistivity has been observed. These are consistent with a dominant dependence of CCE with the concentration of the ionized deep donor, EL2(+).
