Abstract

Adsorption and decomposition of t-butylphosphine: (TBP: (CH3)(3)CPH2) on aGaP(001)-(2 x 1) surface have been studied by low-energy electron diffraction (LEED), high-resolution electron energy loss spectroscopy (HREELS), andtemperature programmed desorption (TPD). It is found that most of TBP is partially dissociated into H and (CH3)(3)CPH at 350 K. The t-butyl radical and isobutylene are evolved from the surface at about 350-450 and 450-550 K,respectively. The activation energy for the radical was estimated to be about 101 kJ/mol. The result obtained, here, is different from that on a GaP(001)-(2 x 4) surface. The decomposition mechanism for TBP on the surface isdiscussed. (C) 2001 Elsevier Science B,V. All rights reserved.
