Why are we talking about the climate crisis and CO2? What do light and a window in the atmosphere have to do with it?
In this lecture, we will take a closer look at the physical basis of the climate crisis - the greenhouse effect. We will learn about the structure of the earth with atmosphere, understand its energy balance and see how different gases react to (sun)light. At the end, it will be clear why we don't want to close the window in the atmosphere and what this might have to do with a down jacket.
![Band structure of 2D semimetal based on HgTe quantum well. Experimental points are obtained from the analysis of the cyclotron resonance in the quasi-classical approximation. Solid lines are predictions of the kp theory with no free parameters. Splitting of the conduction (e1,2) and valence (h1) band is due to the quantum confinement. [J.
