Thermal annealing, irradiation with electrons (25-300 keV), and irradiation with photons (hν = 2.33-3.88 eV) have been used to stimulate the crystallization of isolated amorphous zones in Si, Ge, GaAs, GaP and InP. Transmission electron microscopy a

Isolated amorphous zones were created in Ge by implantation with 50 keV Xe ions. Recrystallization of these zones was stimulated by irradiation with electrons having energy from 25 to 300 keV. The process was studied by using transmission electron mi

Electron transparent GaAs samples were implanted at 300 K and at 90 K with 50 keV Xe ions, which created small (∼8 nm in diameter) amorphous zones in the crystalline structure. These amorphous zones were observed using a transmission electron micro

Amorphous silicon films were prepared by dc reactive magnetron sputtering under a range of hydrogen or deuterium partial pressures approaching the phase transition to full microcrystallinity. Tunneling electron microscopy imaging indicated that these

Spatially isolated amorphous zones in Si, Ge, GaAs, GaP and InP were created by low dose (≈ 1011 cm−2) 50 keV Xe ion implantations. The ion‐implanted samples were subsequently irradiated with electrons or photons which induced recrystallization

Crystallization of spatially isolated amorphous zones in Si, Ge, GaP, InP and GaAs was stimulated thermally and by irradiation with electrons and photons. The amorphous zones were created by a 50 keV Xe+ implantation. Significant thermal crystallizat

Amorphous silicon films were prepared by dc reactive magnetron sputtering under conditions approaching the phase transition to microcrystallinity. Using TEM imaging these films were found to contain clusters of 5 to 50 nm sized Si crystallites embedd

Si and Ge samples of different substrate orientations were implanted with 50 keV Xe+ ions to a dose around 1011 ions/cm2 where the amorphous zones, created by individual ions, remained spatially isolated. The samples were subsequently irradiated at e
