Low-Temperature Facility
The low-temperature facility of the Department of Physics is responsible for supplying the working groups with liquid gases. These are mainly liquid nitrogen and liquid helium. In addition, orders for all required gases can be placed at the low-temperature facility.
Liquid nitrogen
Liquid Nitrogen
Nitrogen cans are filled on Mondays, Wednesdays, and Fridays at approximately 1:00 p.m., provided that enough cans (at least 4) are set out by 11:00 a.m. The nitrogen cans should still be cold, otherwise too much nitrogen is needed to cool them down. The cans should also be tested for function, for example, with respect to their rollers.
Liquid helium
Liquid Helium
The need for helium should be announced early (3-4 days in advance) to ensure effective provision.
![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.
