Abstract

The paramagnetic properties of low‐pressure‐baked (111) Si surfaces interacting with various absorbed gases are investigated by ESR spectroscopic method. Two kinds of surface paramagnetic centres responsible for two ESR lines are found. The ESR P_B‐centres with g = 2.0055 appear on low‐pressure‐baked (111) Si surfaces and disappear in wet atmospheres. The intensity of the ESR P_B‐line increases in O₂ and H₂. The ESR P_A‐centres with anisotropic g‐factor (g ⊥ = 2.0015) appear in O₂ but disappear in H₂ and wet He. The mechanisms for the various behaviours of the two ESR centres are discussed in detail.
