Radiation-induced conductivity ofAl2O3: Experiment and theory

Impedance measurements of thin film ceramics under ion beam irradiation

“…(1) and (2). This value is similar to that of mobility estimated with temperaturedependence RIC model of Al 2 O 3 crystals ($10 À4 m 2 /V/s at RT) [25], and a few orders of magnitude larger than the mobility for Al 2 O 3 powder samples which has been obtained from pulsed electron irradiation experiments (<10 À8 m 2 /V/s) [26]. The smaller carrier mobility may have much to do with excited state molecules.…”

Radiation induced conductivity of ceramic coating materials under 14 MeV neutron irradiation

“…Electrical properties of Al 2 O 3 under radiation environment have been studied by various irradiation experiments [10][11][12][13][14][15][16][17][18][19][20][21]. Radiation induced conductivities for Al 2 O 3 specimens evaluated previously are shown in Fig.…”

Search for radiation-induced electrical degradation in ion irradiated sapphire and polycrystalline Al2O3

“…In RIC, which originates from the formation of electron-hole pairs under ionizing irradiation, decreases with irradiation dose are caused by the creation of charge carrier traps and recombination centers. 42,43 The measured preirradiation conductivity 0 at 450°C was 2.0ϫ10 Ϫ13 S m Ϫ1 . The conductivity during the irradiation P , measured with beam off at 450°C, is shown in Fig.…”
