Electron and donor-impurity-related Raman scattering and Raman gain in triangular quantum dots under an applied electric field
Tiutiunnyk, Anton; Akimov, Volodymyr; Tulupenko, Viktor; Mora-Ramos, Miguel E.; Kasapoglu, Esin; Morales, Alvaro L.; Alberto Duque, Carlos (SPRINGER, 2016)The differential cross-section of electron Raman scattering and the Raman gain are calculated and analysed in the case of prismatic quantum dots with equilateral triangle base shape. The study takes into account their ... -
Optical Absorption and Electroabsorption Related to Electronic and Single Dopant Transitions in Holey Elliptical GaAs Quantum Dots
Alejandro Vinasco, Juan; Alejandro Londono, Mauricio; Leon Restrepo, Ricardo; Eduardo Mora-Ramos, Miguel; Feddi, El Mustapha; Radu, Adrian; Kasapoglu, Esin; Luis Morales, Alvaro; Alberto Duque, Carlos (WILEY-V C H VERLAG GMBH, 2018)The electron states in a holey elliptically shaped GaAs quantum dot are investigated within the effective mass scheme with the use of the adiabatic approximation and the finite element method. The effects of a donor impurity ...
