This upload represents the data used for publication <<Giant THz nonlinearity in topological and trivial HgTe-based heterostructures>> including datasets, images and programming code.

1. Raw_data.rar contains raw data files obtained during transport measurements, two-colour pump-probe experiments(FELBE) and third harmonic generation experiments.

2. Drude_fit.rar contains the result of fitting the complex change in conductivity with Drude fit.

3. Band_structure_calculation.rar contains the result of the fermi energy and dispersion calculations based on kp-method.

4. Theoretical_model_calculation.rar contains the code of the program for the theoretical model for THG and fitting it with experimental data and its result

5. Presentation_Sample_QC0600.pptx contains the information about used sample.
