Incorporation of single molecules or groups of molecules into electronic devices holds great promise for decreasing the size and increasing the packing-density of emerging nano-electronic systems. By wiring a single molecule to two electrodes, direct measurement of charge transport through the molecule can be made with a scanning tunneling microscope (STM). To date most single molecule electronics measurements have focused on the use of gold electrodes. Only a few studies have been involving contacts such as indium tin oxide (ITO) or even metals other than gold. However, it is now important that single molecule electronics research addresses the challenge of other novel two-dimensional (2D) contact materials which will have impact in the eventual implementation of molecular electronics. In this respect, gold has a number of drawbacks; including its non-compatibility with complementary metal-oxide-semiconductor (CMOS) technologies, its mobility and also expense. Introducing other electrodes in the proposed study is aimed towards providing cost effective and industrially scalable materials for integrated single molecule electronics beyond the current limits of miniaturization. Recently, 2D nanomaterials have attracted much attention as a potential material for future electronic and photonic applications. When one of the dimensions is extremely reduced, the two-dimensional nanomaterials exhibit unique properties, such as a transition from indirect to direct semiconductor properties. Inspired by the structural analogue of graphene, 2D layer materials with nature semiconducting properties are ideal candidates to replace gold in future nanoelectronics. Novel 2D materials have already been foreseen as an important future technology and work on these materials has only just begun. The aim of this project is to measure single molecules conductance, also under electrochemical conditions, by the use of 2D materials for single molecule electronic devices, including “white graphene” (hexagonal boron nitride, h-BN), molybdenum disulfide (MoS2) or tungsten disulfide (WS2). We propose to study the electron transport properties of the molecules as a function of temperature, in different solvents and electrolytes, and with and without the electrochemical gate control.
