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.
