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.

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
