通过湿法化学蚀刻或远程氢等离子体处理,在晶体Si中产生几种钛-氢(TiH)络合物。我们确定了两个电活性(${E}_{C}ensuremath{-}0.31$ eV,${E}_{C}ensuremath{-}0.57$ eV)和一个电惰性TiH配合物。被动TiH络合物在高于570 K的温度下解离,导致间隙Ti浓度增加。
Several titanium-hydrogen (TiH) complexes are generated in crystalline Si by wet chemical etching or a remote hydrogen plasma treatment. We identify two electrically active (${E}_{C}ensuremath{-}0.31$ eV, ${E}_{C}ensuremath{-}0.57$ eV) and one electrically inactive TiH complex. The passive TiH complex dissociates at temperatures above 570 K, leading to an increase in the interstitial Ti concentration.
