Field-effect transistors with ultrahigh mobilitiesm

Cambridge University is hiring a first stage researcher within the framework of the UHMob MSCA ITN action (GA n°811284).

Please find a detailed offer and requirements below.


A microscopic understanding of the electron-phonon coupling of charge carriers in high mobility molecular semiconductors to low-frequency intermolecular vibrations is necessary to understand the ultimate limits for charge carrier mobilities in these systems and to design new molecular semiconductors with improved charge transport properties. In this project we will use in-depth characterisation of the charge transport physics, including measurements of  temperature-dependent mobility, Hall effect, thermopower measurement, magnetoresistance etc combined with optical spectroscopy, in particular low-frequency spectroscopy of intermolecular vibrational modes to achieve such an understanding. The work will be carried out in the group of Prof. Henning Sirringhaus at the Cavendish Laboratory of the University of Cambridge

Research field(s): Physics-Semiconductor Physics; Chemistry-Physical chemistry, spectroscopy; Materials Science-Molecular dynamics; Electrical Engineering-Field-Effect transistors
