Abstract: | The neutron radiation effects in GaAs MESFET and HEMT are pre- sented in this paper.According to the mechanism of radiation damage,the rela- tion between device parameters and neutron dose Φis discussed.The device pa- rameters indude physical parameters N_D,N_s,V_s,μ,and electronic parameters I_DS,g_m,V_p,G. |
