Abstract

In this work, we demonstrate the use of laser THz emission microscopy (LTEM) in evaluating the binding energy of locally adsorbed O₂ molecules on 2D materials. The THz waveform can be correlated with the local O2 adsorbate concentration as a function of temperature, allowing the use of LTEM for temperature programmed desorption measurements.
