Inducing micromechanical motion by optical excitation of a single quantum dot - experimental data and evaluation scripts

This data set contains the raw data and the evaluation scripts applied to obtain the results published in "Inducing micromechanical motion by optical excitation of a single quantum dot". For details of the experimental procedure please refer to the main text of the article, as well as the supplementary information.

The main archive (.zip) contains three Python / Jupyter notebooks:

• `cand3_modeV_induced_motion.ipynb` contains the analysis of the main results
• `cand3_modeV_optomechanical_coupling.ipynb` contains an analysis of the opto-mechanical coupling
• `cand3_modeV_thermal_motion.ipynb`contains an analysis of the thermal motion and effective mass

Plots and data that were shown in the main text and supplementary information are written to a subfolder `exports`. Further subfolders contain the evaluated raw data. Two programs have been used to create the raw data.

• `LabOne` by Zurich Instruments has been used to acquire lock-in data from the micro-mechanical oscillator, as well as resonance-fluorescence data from the quantum dot. The data has been stored as comma separated values in (.csv).
   
• Additional data, i.e, the gradient for the optical mechanical motion detection, as well as photo-luminescence spectra of the quantum dot, have been acquired by a selfmade python software `LABCO`. This data has also been stored as  comma separeted values (.csv).

All scripts were written using Python 3.6.9,  and evaluated in Jupyter using IPython 5.5.0. The following non-standard packages (all available through pypi.org) were used during the evaluation:

• `lmfit` 0.9.7
• `matplotlib`2.1.1
• `numpy` 1.13.3
