Abstract

Silicon nanogaps were bridged in situ by grafting 4-ethynylbenzaldehyde to activate the electrodes and coupling 2,6-diaminoanthra-9,10-quinone to link the coatings. The bridged structures exhibit currents of 11-14 nA at 1 V. The process is reversed by soaking in acidified solution, which causes the current to diminish.
