Nonparabolicities and Negative Hole Masses in Quantum Wells
Abstract
It is shown that negative effective masses corresponding to the in plane motion of holes in the fourth group and zinc blend heterostructure quantum wells which are usually attributed to the nonparabolicitiles caused by the repulsion and/or anticrossing of heavy and light hole subbands results in to the competition of two factors: the warping of the bulk energy spectrum and the phase shift of the size-quantized momentum due to heavy-light hole mixing.
