A facile phase transfer procedure is described for the formation of uniform silver metal tips on II–VI semiconductor nanorods. Judicious choice of a functional ligand dimethyl phenol (DMP) which binds to the semiconductor rod in the organic phase enables the transfer of metal ions from the aqueous phase and their reduction onto the nanorod. The nanorod hybrids can be assembled into perpendicula...

This study describes the effect of covalent derivatization of source and drain electrodes with monolayers of organic semiconductors. These monolayers form a template on the metal surface and provide better electronic coupling between the electrode and the semiconductor. We see a large improvement in nanoscale (40-100 nm) transistors only when the monolayer presents functionality that is complem...
