"The effect of uniform electric and magnetic fields on binding energy
and photoionization cross-section of an off-axis hydrogen-like donor
impurity in a QWW, approximated by a cylindrical well of finite
depth, is investigated within the framework of variational approach,"
scientists writing in the journal Superlattices and Microstructures
report.
"The dependencies of the binding energy and photoionization
cross-section on electric field strength, magnetic field induction,
wire radius and impurity position are obtained," wrote V.N. Mughnetsyan
and colleagues, Yerevan State University.
The researchers concluded: "The cases when the polarization vector
of incident radiation is parallel and perpendicular to the wire axis
are both discussed."
Mughnetsyan and colleagues published their study in Superlattices
and Microstructures (Binding energy and photoionization cross section
of hydrogen-like donor impurity in quantum well-wire in electric and
magnetic fields. Superlattices and Microstructures, 2008;44(1):86-95).
Additional information can be obtained by contacting M.G. Barseghyan,
Yerevan State University, Dept. of Solid State Physics, Al Manookian 1,
Yerevan 0025, Armenia.
