Abstract
We present an experimental study of electron wave functions in InAs/GaAs se lf-assembled quantum dots by magnetotunneling spectroscopy. The electronic wave functions have a biaxial symmetry in the growth plane, with axes corre sponding to the main crystallographic directions in the growth plane. Moreo ver, we observed the in-plane anisotropy of the subbands of the quantum wel l. (C) 2001 MAIK "Nauka/Interperiodica".
