Molecular Electronics

Masters/Bachelor Project


Molecular Electronics is one aspect of Nanotechnology that is currently taking the world by storm. It is fueled by the common transistor becoming smaller and smaller, thus leading to difficulties in fabrication methods. Companies such as Hewlett Packard see ‘Molecular Electronics’ as the future and along with University’s they are investing time and money into research in this area. Here at the University of Twente we are also carrying out extensive research in this field.


Recently in collaboration with Harvard University we demonstrated that we could create and characterize diode like supramolecular eletronic devices. This was possible due to the use of our famous ‘Supramolecular Printboard’, in conjunction with the recently published eutectic gallium-indium (EGaIn) technique, which was developed at Harvard University. The supramolecular electronic devices were created by immobilizing dendrimers of various terminal functionality onto the supramolecur printboard, then creating the top metallic contact using EGaIn. By varying the terminal functionality of the dendrimers used we were able to manipulate the ability of the supramolecular device to function as a diode. Due to these findings we have now built an EGaIn system at the University of Twente, and will be using it to further investigate our diode like supramolecular devices.


There are still many different supramolecular factors to investigate and manipulate using the EGaIn technique, thus giving the option of many different project lines. If this sounds interesting to you and would like to have the chance to work at the forefront of this field please show your interest by contacting me,
