Sj. Lee et al., ANISOTROPY EFFECTS ON THE ORBITAL MAGNETISM OF ELECTRONS IN A SPHEROIDAL QUANTUM-DOT, Microelectronic engineering, 43-4, 1998, pp. 99-105
Anisotropy effects in the orbital magnetic susceptibility of electrons
in a spheroidal quantum dot are investigated by applying tilted magne
tic field with parabolic confinement potential. The results show drama
tic phase change; magnetic susceptibility as a function of the electro
n concentration changes from para- or diamagnetic in the case of aniso
tropic quantum dot to diamagnetic only in the isotropic case. Temperat
ure, field and tilted angle dependences are also extensively studied.
