Abstract

Quantum Wells (QW) are of great importance in optoelectronic devices such as LEDs and LASERs, being the emissive layers.Simulating the quantum particles in different QW topologies like rectangular finite potential wells, multiple potential wells, and triangular biased potential well heterojunctions enables faster modeling, theoretical characterization, and more. QVNTVS performs energy level and wavefunction calculations, recombination probability, transition energy, and optical emission computations quickly and accurately. Contrasting with the existing simulators, QVNTVS is an open-source project and can produce solutions for niche problems like potential wells under an electric field, heterojunctions, recombination, and transition matrices. QVNTVS simulates QWs by solving the Time-Independent Schr\"odinger Equation for different potential profiles in a discretized space using the finite-difference method and computes the properties of the device using the extracted information from the solution. The results align with the analytical calculations and the experimental data.
