摘要：

Using Hg/alkyl-chain-monolayer/p-Si devices we find that the type of contact between the chains and the electrodes (chemical bonding or not) is of critical importance for electronic transport across the junctions. As the semiconductor is p-type, the transport is that of holes. In agreement with theory we find that holes tunnel more efficiently through alkyl chains than do electrons.
