Abstract:
Self-assembled monolayers (SAMs) on metal substrates are an important part of modern interfacial physical chemistry and advanced nanotechnology. The robustness of SAMs strongly depends on their thermal stability, which, together with electric conductivity, are the key parameters for their applications in molecular/organic electronics and photovoltaics. In this context, using a multidisciplinary approach, we address here the structure, thermal stability and conductivity of SAMs formed on metal substrates (Au or Ag) using different bonding groups such as thiols, selenols, carboxylic acid and carbenes. Our recent results [1-3] indicate possibility of formation thin well, defined monolayers which exhibit exceptionally high thermal stability and are either highly insulating or highly conductive which makes them an interesting nanomaterial for modification of gate or drain/source electrodes in OFET devices, respectively.

Piotr Cyganik received his PhD in physics from the Jagiellonian University (Kraków, Poland) in 2002. As a postdoc he spend almost 4 years working first at the St Andrews Univrsity (UK), and later as the Alexander von Humboldt fellow at the Bochum University (Germany). In the end of 2005 he received adjunct position back at his alma mater where he is now professor in physics at the Department of Physics of Nanostructures and Nanotechnology. Together with his group of PhD and masters students he works on analysis of structure and properties of monomolecular organic films formed on a solid substrates. In his experiments he uses combination of microscopic, spectroscopic and spectrometric techniques and collaborates with other groups in USA (Harvard University) and Europe (Heidelberg University, Imperial College London, Jena University, Graz University). He is a coauthor of 58 papers in this area of research which have been cited over 2000 times with the h-index of 27.
