    Together with Daniel Groll
    Mondays 10-12 in IG1 - 718

    Description:

    This lecture introduces the fundamentals of optical spectroscopy, covering theoretical basics and experimental techniques. Optical spectroscopy is crucial in current research, enabling analysis of light-matter interactions and material properties. In addition to the discussion of various relevant spectroscopy methods, we will provide examples of current and on-going research at the University of Münster within the field of optical spectroscopy of solid state nanosystems.

    Examples of discussed techniques:

    Photoluminescence
    Absorption spectroscopy
    Raman spectroscopy
    Coherent control
    Heterodyne four-wave mixing
    Near-field spectroscopy
    Photon correlation experiments (Hanbury-Brown-Twiss)

    Aspects of the theory that is covered:

    Quantization of the light field
    Light-matter interaction
    Basics of open quantum systems
    Detector theory and correlation functions

    Basic data:

    2 SWS - 2 credit points
    Mondays 10 c.t. in IG1 - SR 85
    The lecture is part of the Master Physics program

    Description:

    This lecture deals with light matter interaction on the nanoscale.

    We will learn how light can be focused beyond the diffraction limit to achieve nanoscale resolution. We will focus on near-field techniques like scattering type scanning near-field optical microscopy (s-SNOM), nanoscale fourier transform infrared spectroscopy (nano-FTIR), as well as tip-enhanced Raman (TERS) and photoluminescence (TEPL). These techniques are based on light scattering at an atomic force microscope tip and can be used to investigate a wide range of materials (from 2D semiconductors and polymers over molecules to soft biological matter) on the nanoscale.

    After understanding these techniques we will discuss recent applications focusing on 2D materials.
