Thermal Disorder in Adsorbed Cl on Si(100)

Abstract

Thermal broadening of C1(+) ESDIAD patterns, related to the vibrational motion of the adsorbate, has been investigated by subtraction of patterns measured at different temperatures. In the case of C1 on Si(100), the observed difference pattern between 130 K and 305 K indicates that azimuthally isotropic motion of C1 occurs about the most probable Si-C1 bond direction. Equal distributions from the in-plane and out-of-plane bending motions are observed, correlating with the approx 200 /cm frequencies associated with these motions.
