Objective Nanoscale integrated electronics requires building blocks with controlled functional properties. Tertiary inorganic nanowires made up of molybdenum, sulphur and iodine (MoSI) are a newly emerging class of one-dimensional objects with a straightforward, sca lable synthesis. In nanoelectronics they are to date the only viable alternative to Carbon nanotubes (CNTs). Contrarily to CNTs, they are soluble in a variety of solvents and tend to be monodisperse with all nanowires of a given stoichiometry having identical electronic properties. In order to exploit the functionality of 1D materials in possible nanoelectronic devices such as single-electron or ballistic transistors, the non-equilibrium electron dynamics has to be understood.The goal of this project is a comprehensive investigation of the fast and slow electronic processes occurring in MoSI nanowires. This means applying an external stimulus to drive the electrons out of their equilibrium distribution and monitoring the relaxation processes. The focus is o n light and electric fields/currents as external stimuli. Specifically the project addresses ultra-fast relaxation processes, long lived excited states and the effect of electric fields. The processes will be investigated as a function of temperature (room temperature to liquid helium temperature) and excitation density.The tools for investigation will be ultra-fast pump-probe spectroscopy, photomodulation and electromodulation as well as a combination of pump-probe with further modulation of parameters such as an applied field. The detection will cover the visible, most of the infrared and THz spectral ranges.
