Korea-Tübingen PhD Program: Project 13/2024:
PhD Project Title: Enhanced optical spectroscopy and microscopy of organic molecules

Topic Description: It has been shown that the electronic structures of self-assembled monolayers or two-dimensional transition metal dichalcogenide monolayers can be influenced by their morphologies. In this fundamental science-oriented project, polarized Raman and fluorescence spectroscopy will be applied to derive the molecular orientation, and local structure order of the thin films. Second harmonic generation microscopy and two photon fluorescence will be used to study the defects, and grain boundaries. By imaging the above signals in the Fourier plane, one will further correlate the intensity and energy of the signal with its angular information. In the case of very weak optical signals, different enhancement strategies will be explored making use of the electromagnetic enhancement and chemical enhancement mechanisms. The PhD candidate will get insight into the relationship between the film morphology and their electronic structures. The candidate will also obtain experiences of working with optics and different types of optical microscopes.
