What is Role of electrode metallization in performance of semi-insulating GaAs radiation detectors about?

In the present work, a comparative study of semi-insulating (SI) GaAs radiation detectors with different blocking (Schottky) and ohmic contact metallization is presented. The detectors fabricated from ''detector-grade'' bulk SI GaAs are characterized by current-voltage measurements and their detection performance is evaluated from pulse-height spectra of 241 Am and 57 Co g-sources. Observed results are evaluated and discussed. Importance of the optimized electrodes technology of SI GaAs detector with good performance is demonstrated.
