Quinn, Bernadette M. Electrical conductivity Monolayers Nanoparticles Redox reactions Thin films This article reports the use of the scanning electrochemical microscope (SECM) to investigate the electronic properties of Langmuir monolayers of alkane thiol protected gold nanocrystals (NCs). 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. 2025-11-26T08:18:53Z 2025-11-26T08:18:53Z 2004-06 info:eu-repo/semantics/article 0002-7863 https://hdl.handle.net/10259/11104 10.1021/ja0493188 1520-5126 eng Journal of the American Chemical Society. 2004, V. 126, n. 22, p. 7126–7132 https://doi.org/10.1021/ja0493188 info:eu-repo/semantics/openAccess American Chemical Society
