QVNTVS: Open-Source Quantum Well Simulator

• QVNTVS is an open-source project based in Python for modeling and simulating quantum wells of different shapes and heterojunctions including analyzing energy levels, wavefunctions, recombination probabilities, optical phenomena and more.
• QVNTVS is an original work of Barbaros Şair.
• The paper of QVTNVS is published in arXiv.
• To read it: https://arxiv.org/abs/2508.07792

Key Features:

• Simulate quantum wells of different shapes and biasings fast, efficiently, and without any licensing problem.
• Analyze Quantum well behavior under reverse-bias, equilibrium, and forward-bias modes including electric field effects.
• Obtain recombination probabilities of carriers and related transition energies.
• Get optical emission spectrum.
