Nanoscale metal/self-assembled monolayer/metal heterostructures
TL;DR: In this article, a self-assembled monolayer of 4-thioacetylbiphenyl with nanoscale area was investigated and the experimental results showed that thermal emission of electrons over a barrier of 0.22 eV dominates electron injection from Ti into the organic layer while the transport for electron injection was satisfied by the formula for hopping conduction.
