Whitesides. 2012. The Rate of Charge Tunneling through Self-Assembled Monolayers Is Insensitive to Many Functional Group Substitutions. Angewandte Chemie International Edition 51, no. 19: 4658–4661.1433-78511521-3773http://nrs.harvard.edu/urn-3:HUL.InstRepos:11956909Insensitivity: A series of molecules containing a common head group and body as well as structurally varied tail groups (-R) has been used in junctions with the structure Ag/S(CH2)4CONH(CH2)2R//Ga2O3/EGaIn to study the rates of charge transport by tunneling. Changing the structure of R over a range of common aliphatic, aromatic, and heteroaromatic organic groups was found to not significantly influence the rate of tunneling (see plots; the dashed lines represent calibration standards).en-UScharge transportmolecular electronicsmonolayerstunnel junctionsJournal Article2014-03-2010.1002/anie.201201448
