Adsorption and decomposition of triethylphosphine (TEP) and tertiarybu
tylphosphine (TBP) have been studied using XPS, HREELS, and TPD, TEP i
s adsorbed molecularly on the Si(001) surface at RT and some of it is
desorbed as a molecule between about 50 and 300 degrees C. The other i
s decomposed and C2H4 is evolved between about 150 and 500 degrees C.
For TBP, it is suggested to be partially dissociated at RT and C4H8 is
evolved between about 70 and 450 degrees C. No carbon left on the sur
faces is detected within the detection limit of AES after the TPD meas
urement for TEP and TBP. The decomposition mechanisms of TEP and TBP o
n the surface are proposed.
