“…A favoured model for the 111 platelet (see Section 8), deduced from both transmission electron microscopy (TEM) studies [141] and theory [142], suggests that H forces apart the two nearby (111) planes by about 3Å, and saturates the two surfaces of dangling bonds thus formed. This ideal structure does not involve any silicon vacancies.…”

“…1 An infrared-absorption experiment has shown that hydrogen introduced in to p-or n-type silicon forms complexes with acceptor or donor atoms. 2 Other experimental results and theoretical calculations have suggested that ͕111͖ platelets [3][4][5][6][7][8] and a metastable diatomic hydrogen complex [9][10][11] are formed in heavily doped n-type silicon.…”

We have found that hydrogen exists in molecular form in crystalline silicon treated with hydrogen atoms in the downstream of a hydrogen plasma. The vibrational Raman line of hydrogen molecules is observed at 4158 cm Ϫ1 for silicon samples hydrogenated between 180 and 500°C. The assignment of the Raman line is confirmed by its isotope shift to 2990 cm Ϫ1 for silicon treated with deuterium atoms. The Raman intensity has a maximum for hydrogenation at 400°C. The vibrational Raman line of the hydrogen molecules is broad and asymmetric. It consists of at least two components, possibly arising from hydrogen molecules in different occupation sites in crystalline silicon. The rotational Raman line of hydrogen molecules is observed at 590 cm Ϫ1 . The Raman band of Si-H stretching is observed for hydrogenation temperatures between 100 and 500°C and the intensity has a maximum for hydrogenation at 250°C. ͓S0163-1829͑97͒09235-7͔

“…Of the models so far suggested for the 111 platelet, TEM studies [9] and calculations [10], favour the structure with a pair of hydrogen atoms saturating each broken bond between (111) planes displaced apart by ≈ 3Å. This structure does not include any silicon vacancies.…”

We present the results of first principle calculations on the behaviour of molecular hydrogen within crystalline silicon, both as an isolated species, and within defects in the material. These results are compared with recent experimental infra-red and Raman data obtained for silicon treated by either hydrogen plasma or soaked in hydrogen gas. The effect of Fermi-level position on the diffusion barrier of molecular hydrogen within silicon is also discussed.Interest in the behaviour of molecular hydrogen within silicon has been fuelled by the recent observation of H 2 sited at three distinct environments within crystalline silicon by infrared [1,2]
