Shallow donors in a triple graded quantum well under electric and magnetic field
(ELSEVIER SCIENCE BV, 2003)
The binding energy of the donor impurity in triple graded GaAs-(Ga,Al)As quantum wells is calculated by using a variational approach. The results have been obtained in the presence of a uniform magnetic and electric field ...
Shallow donors in the triple-graded quantum well under the hydrostatic pressure and external fields
(ELSEVIER SCIENCE BV, 2006)
The binding energy of the donor in the triple-graded GaAs-(Ga,Al)As quantum well under the hydrostatic pressure, electric and magnetic fields are calculated by using a variational approach. The results have been obtained ...
Hydrogenic impurities in graded GaAs-(Ga,Al)As quantum-well wires in an electric field
(ELSEVIER SCIENCE BV, 2002)
The electric field dependence of polarizability and binding energy of shallow-donor impurities in graded quantum-well wires is calculated by a variational method and in the effective-mass approximation. We have considered ...
