ELECTRONIC G-FACTOR IN BIASED QUANTUM-WELLS

A theory of the Zeeman splitting of electronic spin states in biased q uantum-well structures has been developed. The g factor tensor has bee n calculated as a function of the applied electric field and the well width. The longitudinal g factor has been shown to be more sensitive t o the field than the transverse, or in-plane, component. For a fixed e lectric field and increasing the well width, the g factor components s aturate towards the corresponding values for a single heterojunction. The theoretical results has been compared with available experimental data. (C) 1997 Published by Elsevier Science Ltd.
