Shallow donor impurity binding energy in the V-shaped quantum well under the crossed electric and magnetic fields
(ELSEVIER SCIENCE BV, 2005)
We have calculated variationally the ground state binding energy of a hydrogenic donor impurity in V-shaped quantum well (VQW) or full-graded GaAs/Ga1-xAlxAs quantum wells in the presence of crossed electric and magnetic ...
Binding energies of shallow donor impurities in different shaped quantum wells under an applied electric field
(ELSEVIER SCIENCE BV, 2003)
We present a variational method to compute the binding energies for a hydrogenic impurity located at the center of the finite parabolic (PQW), V-shaped (VQW or full graded well) and square (SQW) GaAs-Ga1-xAlxAs quantum ...
Geometrical effects on shallow donor impurities in quantum wires
(ELSEVIER SCIENCE BV, 2003)
We have studied theoretically the impurity binding energy for wires of different shapes (V-shaped quantum wire (V-QWR) and rectangular wire) with a variational procedure without using any coordinate transformation. The ...
