Reports Summarize Quantum Dots Study Results from Dokuz Eylul University (Electron-related optical responses in triangular quantum dots)

July 22, 2014

By a News Reporter-Staff News Editor at Physics Week -- New research on Quantum Dots is the subject of a report. According to news reporting originating from Izmir, Turkey, by VerticalNews correspondents, research stated, "The linear and nonlinear coefficients for the optical absorption and relative refractive index change associated with intersubband transitions of electrons in the conduction band of a two-dimensional quantum dot of triangular shape are calculated for x-polarization and y-polarization of the incident light."

Our news editors obtained a quote from the research from Dokuz Eylul University, "Both the effective mass and parabolic band approximations have been considered. The results show that the increase in the size of the triangular quantum dot leads to the expected fall of the intersubband energy transition and that there is an increment in the values of the associated off-diagonal electric dipole moment matrix elements."

According to the news editors, the research concluded: "All this reflects in the increase of the amplitude of the nonlinear optical absorption resonant peak, as well as in the growth of the total relative refractive index in the system."
