Abstract

We have performed electrical transport measurements on thin epitaxial buried CoSi2 layers in (111) and (100)Si with thicknesses ranging from 11.5 to 110 nm. The resistivity as a function of temperature exhibits metallic behaviour. The increase of residual resistivity with decreasing thickness can be explained by quantum mechanical weak localization effects induced by the interface roughness. This is supported by magnetoresistance measurements which provide long phase coherence lengths of 1Փ, ≈ 0.75 μm in (111)Si and 1Փ, ≈ 2.3 μm in (100)Si at 4.2 K.
