Diamond Miner

Extract Coulomb diamond information from a provided measurement dataset.

Installation

To install this package you must first activate your environment (example below if you are using conda),

conda activate ENV_NAME

Then you can build the package using setup.py which will generate some folders in your repository,

python setup.py bdist_wheel sdist

Then using pip to install the package based on the build folders created from the command above,

python -m pip install . 

Usage

Please see demo.ipynb for usage. You can try it out on the demo_data_(1/2).txt prepared datasets.

Results

Below are two results that can be reproduced in the demo.ipynb: (1) Coulomb diamonds and estimated dot information, (2) Charge temperature information.
