All aspects of the mechanically controllable break-junction technique (MCBJ) and how it can be used to investigate charge transport on the single-molecule scale are demonstrated. Its working principle, the sample fabrication, the measurement setup, and the experimental procedures are explained. The video concludes with some of the results that were obtained and their interpretation.
van der Zant Group | TU Delft, The Netherlands
Herre van der Zant finished his PhD in 1991 under the supervision of Hans Mooij at the Delft University of Technology, The Netherlands. His thesis was concerned with experiments on classical and quantum phase transitions in Josephson junction arrays. In subsequent years, he worked on superconducting electronics and mesoscopic charge density waves. In 2005, he cofounded the Molecular Electronics and Devices (MED) group in the Kavli Institute for Nanoscience of the Delft University of Technology. As a professor in this group, his research focuses on transport through single molecules and nano-electromechanical systems. There is a close collaboration between the group of Herre van der Zant and Jan van Ruitenbeek from Leiden University in the research field of mechanically controllable break-junction techniques. The successful collaboration has resulted in several joint publications.
Diana Dulic has ten years of experience with transport measurements through single molecules using mechanically controllable break-junction techniques and is considered to be one of the pioneers of the field.
Mickael L. Perrin graduated with Honor (Cum Laude) from the TU Delft. He did his masters project on MCBJ experiments and started his PhD in the Molecular Electronics and Devices group in March 2011.
The original research article is published in the Open Access Beilstein Journal of Nanotechnology and is part of the Thematic Series Transport through molecular junctions.
