概要 It is known that amorphous Si layer formed on a crystalline Si substrate is effectively crystallized by high-energy ion irradiation at relatively low temperature. Here, point defects such as vacancy and interstitial pairs created by elastic collisions in beam irradiation plays an important role in the low temperature crystallization process. It is in addition pointed out that electron-hole pair excited by electronic inelastic scattering probably contributes to the single crystallization so far. In this study, we investigated the effect of the inelastic energy deposition to beam-induced epitaxial crystallization by comparing the epitaxial crystallization by the high-energy electron to that by proton irradiation.
