The Binding Energy and Magnetic Susceptibility of an Off-Centre D 0 Donor in the Presence of a Magnetic Field in a GaAs Quantum Dot with Gaussian Confinement: An Improved Treatment
The binding energy and susceptibility of an off-centre neutral hydrogenic donor impurity (D 0) trapped in a three-dimensional Gaussian quantum dot in the presence of an applied magnetic field are obtained by a variational method with an improved wave function. The results are obtained as a function of the quantum dot size, position of the impurity and the confinement strength.
