description: The subject of the graduate qualification work is InP/GaInP2 single quantum dots. The given work is devoted to study the Wigner localization and states of the 2D electronic system at high temperature in lateral quantum dots. We used photoluminescence spectra of a single InP/GaInP2 quantum dot (QD) having three electrons to measure the magnetic field (B) dispersion, i.e., shift of the emission lines, of occupied quantum states in a range between B = 0 and 10 T at 30 K. The measurements show the formation of a molecular structure at high temperature and its transition to a Â«puddleÂ» structure with a decrease of localization size from 110 nm to 70 nm. Fock-Darwin spectrum fitting shows a decrease of the dispersion, i. e., cyclotron frequency, that are interpreted as the formation of an anyon structure in a QD with fractional charge 1/5, 2/3, 1/2 and a built-in magnetic field Bin = -3 T. For the analysis and construction of experimental magneto-photoluminescence data and fitting of the theoretical Fock-Darwin spectrum, specialized software and mathematical software Origin2018 was used.
