PHYSICS: RESEARCHERS FROM YEREVAN STATE UNIVERSITY DISCUSS FINDINGS IN PHYSICS
Science Letter
September 30, 2008
According to recent research from Yerevan, Armenia, "The absorption
of light in an ensemble of non-interacting cylindrical quantum dots in
the presence of a magnetic field is discussed using a model consisting
of dots with rectangular infinitely-high potential barriers."
"The ensemble’s absorption coeficient is calculated – as well
as the threshold frequency of absorption – as a function of the
applied magnetic field and the quantum dot size. Theoretical results
are compared with experimental data on magneto-luminescence in an
In0.53Ga0.47As/InP cylindrical quantum dot system," wrote A.K. Atayan
and colleagues, Yerevan State University (see also Physics).
The researchers concluded: "In addition, using a perturbation theory
framework, the influence of excitonic effects on the behaviour of
the electron-hole energetic spectrum of said system is discussed."
Atayan and colleagues published their study in European Physical
Journal B (Magneto-absorption in cylindrical quantum dots. European
Physical Journal B, 2008;63(4):485-492).
