Signatures of Majorana fermions in hybrid superconductor-semiconductor nanowire devices

Science 336, 1003-1007 (2012)


---------------------------------------------

Author contributions to this repository:

Data were obtained between November 2011 and March 2012 by KZ, VM and SF. The files in the repository were organized by SF. 

LK supports making data files available but has not contributed and has not checked the quality of the files in this data repository.

---------------------------------------------

Original data obtained at the time of measurement are in the \Data folder. The folder also contains data selected for the paper.

The repository also includes measurement logs (\Logs), and some plotting scripts (\Scipts)

Folder \Analyses contains powerpoint files made at the time of measurement helpful for data overview

---------------------------------------------

Devices studied:

N-nanowire-S device 1 (chip name 6F2 device 3 in this repository)
Device measured in the dilution refrigerator 'Oxford 200s', at the same time as device 3

N-nanowire-S device 2 (chip name 6F4)
Device measured in the dilution refrigerator Frossati MCK-50 'Fristi', equipped with a 9-3-1 T vector magnet)

M-nanowire-S device 3 (chip name 6F2 device 1 in this repository)
Device measured in the dilution refrigerator 'Oxford 200s', at the same time as device 1

N-N devices (Chip name 6F8)
Devices measured in Frossati MNK fridge 'Big Frossati'

S-S devices (Chip name 6E5)
Devices measured in the dilution refrigerator 'Oxford 200s'

---------------------------------------------


Data for devcies are obatined using QTLab: https://github.com/heeres/qtlab

Most data for device2 are obtained using Igor Pro: https://www.wavemetrics.com/


---------------------------------------------
Data file types:

data_NNN.dat  - the original data file obtained at the time of the experiment
dataNNN.py    - the original QTLab data acquisition script saved with data
data_NNN.set  - settings of measurement instruments at the time of measurement
data_NNN.meta - auxillary file necessary for plotting data using SpyView (see below) 


NNN stands for dataset number, automatically indexex by QTLab

--------------------------------------------

How to plot data:

1) Spyview - a free data plotting program written by Gary Steele

Data in this repository can be simply dropped into Spyview for plotting. 

Spyview also produces and can read .mtx files which are available for some of the data in this repository.

https://nsweb.tn.tudelft.nl/~gsteele/spyview/


2) QTPlot - a Python plotter written by Ruben van Gulik

Data in this repository can be directly opened with QTPlot, which will read axis labels.

Note: requires PyQT4
