Abstract
We find that TEP is adsorbed molecularly and TBP is partially dissocia ted at RT. Some of the TEP molecules on the surface are desorbed and t he others are decomposed into C2H4 and H-2, evolving from the surface. The desorption peak of the TEP molecule is increased in intensity und er hydrogen ambience. For TBP, the TPD peaks for C4H9 radical and C4H9 are found. The peaks of C4H9 radical and C4H8 are increased and decre ased in intensity, respectively, under hydrogen ambience. The decompos ition mechanisms of TEP and TBP on the GaP(001) surface are discussed. (C) 1997 Elsevier Science B.V.
