AB  - Inelastic electron tunneling spectroscopy (IETS) [R. C. Jaklevic and J. Lambe, Phys. Rev. Lett.17, 1139 (1966); R. G. Keil et al., Appl. Spectrosc. 30, 1 (1976); K. W. Hipps and U. Mazur, J.Phys. Chem. 97, 7803 (1993); U. Mazur et al., Anal. Chem. 64, 1845 (1992); P. K. Hansma,Tunneling Spectroscopy (Plenum, New York, 1982)] measurements are performed on Sinanowire (NW)/SiO2/Al NW tunnel junctions. The tunnel junction area is 50  120 nm andtunneling occurs across a 10 nm thick SiO2 layer. IETS measurements are performed at 300 K forammonium hydroxide (NH4OH), acetic acid (CH3COOH), and propionic acid (C3H6O2)molecules. The I–V, dI/dV–V, and d2I/dV2–V characteristics of the tunnel junction aremeasured before and after the adsorption of molecules on the junction using vapor treatment orimmersion. Peaks can be observed in the d2I/dV2–V characteristics in all the cases followingmolecules adsorption. These peaks may be attributed to vibrational modes of N–H and C–Hbonds.
