A substantial increase in monolayer conductivity upon mechanical compression of the Au NC monolayer is reported for the first time. This may be the room temperature signature of the insulator to metal transition previously reported for comparable silver NC monolayers. Factors influencing the conductivity of the monolayer NC array are discussed. 0002-7863 https://hdl.handle.net/10259/11104 10.1021/ja0493188 1520-5126 Electrical conductivity Monolayers Nanoparticles Redox reactions Thin films Electron Transport in Two-Dimensional Arrays of Gold Nanocrystals Investigated by Scanning Electrochemical Microscopy
