Stereo-isomerism controls surface reactivity: 1-chloropentane-pairs on Si(100)-2×1

Author affiliations

Abstract

Chloropentane forms asymmetric (‘A’) and symmetric (‘S’) pairs on Si(100)-2×1, differing in the direction of curvature of one pentane tail. Surprisingly this renders the rate of thermal reaction of ‘A’ fifteen times greater than ‘S’ in chlorinating room-temperature silicon. Correspondingly, for electron-induced reaction the energy threshold for A is 1 eV less than for S.
