ABSTRACTIsolated amorphous zones produced in GaAs, GaP, Si, and Ge by the implantation of 50 keV Kr+ or Xe+ ions have been induced to recrystallize under the influence of the electron beam in the transmission electron microscope. This effect has been investigated as a function of electron irradiation temperature and beam energy in the TEM. Temperature effects were investigated through irradiations performed at 30 and 300 K. The electron energies used ranged from 50–300 keV in the 300 K experiments and 200 keV electrons were used at 30 K.Recovery was induced in all of the materials even at electron energies below the threshold displacement energy indicating production of point defects within the crystalline material is not required to induce regrowth. In GaAs and GaP, recovery occurred for all electron energies studied, down to 50 keV. In Si, the beam induced regrowth rate approaches zero at an energy of 80 keV with the recovery rate increasing with increasing electron energy. At 30 K, the 200 keV electron beam induced recrystallization in all cases studied (GaAs, GaP, and Si).

ABSTRACTCuTi was irradiated with 1-MeV electrons and Kr+ ions simultaneously at temperatures from 10 to 423 K. Retardation of Kr+-induced amorphization was observed with simultaneous electron irradiation at 295 and 423 K. The retardation effect increased with increasing irradiation temperature and relative electron-to-Kr dose rate. In contrast, simultaneous irradiation below 100 K showed an additive effect of electron- and Kr+-induced amorphization. The results can be explained by the mobility point defects introduced by electron irradiation interacting with Kr+-induced displacement cascades.

AbstractHermetically metal coated fibers are candidates for applications at high temperatures. To date, various metals with melting point up to 1400 °C have been used to coat fibers by the freezing technique. However, the major problems consist of ensuring mechanical reliability and acceptable optical losses in metal coated fibers at high temperatures. We present an experimental study of the temperature effects at 20 – 1050 °C on the performance of optical fibers with copper coating. Specific fiber degradation mechanism have been revealed
