An overview is given on results from a hybrid molecular/MOSFET that is sensitive to the presence of molecular layers attached to its surface. Numerical simulations of the device suggest that the shift in threshold voltage of the device after attachment of the molecular layer is due to protonation of the native oxide, and this is explained in terms of the greater acidity of the caboxylic acid.
