|Title:||Self-similarity And Anti-self-similarity Of The Effective Landé G Factor In Gaas-(ga,al)as Fibonacci Superlattices Under In-plane Magnetic Fields|
De Dios-Leyva M.
|Abstract:||A theoretical study of the effects of in-plane magnetic fields on the Landé g factor associated to conduction electrons in GaAs-(Ga,Al)As Fibonacci superlattices is presented. We have used the Ogg-McCombe effective Hamiltonian, which includes nonparabolic and anisotropy effects, in order to describe the electron states in the Fibonacci heterostructure. We have expanded the corresponding electron envelope wave functions in terms of harmonic-oscillator wave functions, and obtained the Landé g factor for magnetic fields related by even powers of the golden mean τ=(1+5)2. Theoretical results for GaAs-(Ga,Al)As Fibonacci superlattices, under magnetic-field values scaled by τ2n, clearly exhibit a self-similar (for even n) or anti-self-similar (for odd n) behavior for the Landé g factors, as appropriate. © 2006 The American Physical Society.|
