摘要: An extended theoretical approach for calculating the 1s-1s electronic transition in spherically layered semiconductor quantum dots is presented. The extension over common effective-mass approximation includes implementation of Coulomb interaction and finite potential wells at particle boundaries. calculations are carried out quantum-dot well CdS/HgS/CdS compared to recently available experimental results. wave functions electrons holes spreading entire structure probabilities presence different layers, as outside surrounding dielectric water,
