The current voltage (I-V) analysis using Eq 1 as the first recognized SLM expression in tunneling junction analysis achieves to unveil various features of the molecular junctions. For example, Luka-Guth et al studied the role played by the solvent in electronic transport in molecular junction, the junction analysis help them to make a reasonable conclusion on differentiated solvent conductance with that of molecular junction . On the other hand, Zotti et al revealed the effect of anchoring group in molecular junction by examining the influence of moleculemetal contact interaction in molecule junction . Tunneling junction analysis based on simplified I-V relation have been currently growing in popularity due to their simplifications. For example, Emanuel and coworkers reported their study using Eq 2 in junction analysis to compare the effect of thiols and isocyanide as anchoring group in 1,4 benzene dithiols and 1,4 benzene diisocyanide molecular junction. The conclusion drawn is the same as Zotti et al , though the molecule differ by one benzene ring, but the extracted key parameters appear to be significantly different. Eq 3 has also attracted many studies, and it closely related to another popular method in characterizing the energy offset in the molecular junctions, i.e. transition voltage spectroscopy (TVS) . TVS enables determination of transition voltage (V 𝑡𝑟𝑎𝑛𝑠 ) in a Fowler-Nordheim plot (F-N). However, as revealed by Vilan et al later on, V 𝑡𝑟𝑎𝑛𝑠 is actually not a sign of the F-N transition, rather it is a mathematical sign of none linearity of I-V plot. Baldea derived an approximated relation between V 𝑡𝑟𝑎𝑛𝑠 and energy offset based on Eq 3, i.e.eV 𝑡𝑟𝑎𝑛𝑠 = 2∆𝜀/√3, which later on was found to be effective and acceptable method in analyzing molecular energy levels. Frisbie and coworkers have extensively used this method to examine molecular junction of different molecules on metal contacts (Ag, Au and Pt) and explore fascinating junction characteristics and features. However, when making comparison of extracted parameters with other methods like Eq 2, we observed substantial difference in energy offset (ε0) for oligophenylene dithiols (OPD1) analyzed using Eq 3 (Frisbie et al. results) and Eq 2 (Emanuel et al results ) which was 0.87 eV and 0.26 eV respectively on Au/Au electrode. The observed variation can be attributed to different factors, such as adopted method for I-V measurement, among which the most important one is the applicability of SLM modeling methods. In addition, SLMs have also been applied to thermoelectricity studies, such like extracting the Seebeck Coefficient, which can help to understand electronic structure of the molecular junction, i.e., Fermi level of the electrodes with respect to the HOMO or LUMO levels of the molecules, through determining the type of charge carriers (either p-or n-type) .
