摘要：

A Raman-scattering study of molecular hydrogen trapped within {111}-oriented platelets in Si is presented. The Raman lines originating from the rotational transitions S-0(J) with J = 0, 1, 2, and 3 are identified at 353 (1), 587(1), 815(1), and 1034(2) cm(-1), respectively. At low temperatures, ortho-to-para conversion of H-2 trapped within platelets is observed and suggested to be caused by the interaction of H-2 molecules. The Raman band at 4150 cm(-1) originates from vibrational transitions of H-2 within platelets. The shape of the band is composed of ortho-and para-H-2 species of two different platelet structures.
