&lt;p&gt;Growth of PbTe nanowires by Molecular Beam Epitaxy&lt;br&gt;
Authors: Sander G. Schellingerhout, Eline J. de Jong, Maksim Gomanko, Xin Guan, Yifan Jiang, Max S.M. Hoskam,&lt;br&gt;
Sebastian Koelling, Oussama Moutanabbir, Marcel A. Verheijen, Sergey M. Frolov, Erik P.A.M. Bakkers&lt;/p&gt;

Spin and Orbital Spectroscopy in the Absence of Coulomb Blockade in Lead Telluride Nanowire Quantum Dots&lt;br&gt;
Authors: M. Gomanko, E.J. de Jong, Y. Jiang, S.G. Schellingerhout, E.P.A.M. Bakkers, and S.M. Frolov&lt;/p&gt;

Content of this repository:&amp;nbsp;&lt;/p&gt;

&lt;p&gt;Readme file.&amp;nbsp;&lt;/p&gt;

Original data obtained at the time of measurement separated into 3 folders from different chips/cooldowns&lt;br&gt;
Data from devices 1,3 and 4 can be found in &amp;quot;RawData/PbTe_chip1&amp;quot;, device 2 in &amp;quot;RawData/PbTe_chip2&amp;quot; and devices 5-8 in &amp;quot;RawData/PbTe_GBg&amp;quot;&lt;/p&gt;

&lt;p&gt;/Measurement notebooks/&lt;br&gt;
OneNote notebook with 4 different sections for 3 chips (two sections for backgate chip). Pages in these sections contain the device number in the name.&lt;br&gt;
Also, the same notebook is exported in pdf format for convenience.&lt;/p&gt;

&lt;p&gt;/Data processing/&lt;br&gt;
Readme file, Jupiter notebooks, data files, and pictures, that were&amp;nbsp;used to extract g-factors for different field orientations in device2.&lt;/p&gt;

&lt;p&gt;/Data summaries/&lt;br&gt;
Powerpoints, that were used to overview data during the measurement stage.&lt;br&gt;
Not all data from these powerpoints are present in the repository or paper (specifically excluding early data used in &amp;quot;additional backgate devices.pptx&amp;quot; and &amp;quot;PbTe 3rd device.pptx&amp;quot;).&lt;/p&gt;

&lt;p&gt;Data file types:&lt;/p&gt;

&lt;p&gt;data_NNN.dat &amp;nbsp;- the original data file obtained at the time of the experiment&lt;br&gt; &amp;nbsp;&amp;nbsp;&amp;nbsp;- the original QTLab data acquisition script saved with data&lt;br&gt;
data_NNN.set &amp;nbsp;- settings of measurement instruments at the time of measurement&lt;br&gt;
data_NNN.meta - auxillary file necessary for plotting data using SpyView (see below)&amp;nbsp;&lt;br&gt;
data_NNN.MTX &amp;nbsp;- a simple 2D/3D matrix format developed for Spyview&lt;/p&gt;

&lt;p&gt;NNN stands for dataset number, automatically indexed by QTLab&lt;/p&gt;

How to plot data:&lt;/p&gt;

&lt;p&gt;1) Spyview - a free data plotting program written by Gary Steele&lt;/p&gt;

&lt;p&gt;Data in this repository can be simply dropped into Spyview for plotting.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;Spyview also produces and can read .mtx files which are available for some of the data in this repository.&lt;/p&gt;


2) QTPlot - a Python plotter written by Ruben van Gulik&lt;/p&gt;

&lt;p&gt;Data in this repository can be directly opened with QTPlot, which will read axis labels.&lt;/p&gt;


&lt;p&gt;Note: requires PyQT4&lt;/p&gt;</subfield>
