Abstract
We have studied the adsorption of ammonia on Si(111) using surface vibrational spectroscopy and photoemission spectroscopy. The results show that is adsorbed primarily as a nondissociated molecule at room temperature. These findings are in contrast with recent results on Si(100), which suggest that a large fraction of the adsorbed ammonia molecules dissociates.
