Iv. Kukushkin et al., STRONG REDUCTION OF THE FERMI ENERGY OF 2-DIMENSIONAL ELECTRONS IN A PARALLEL MAGNETIC-FIELD, JETP letters, 60(7), 1994, pp. 556-560
A strong reduction of the Fermi energy of two-dimensional electrons in
a parallel magnetic field was directly observed in a magnetooptical e
xperiment. The reduction is higher for a lower electron concentration.
The observed effect can be associated with a modification of the ener
gy spectrum of two-dimensional electrons by an in-plane magnetic field
