P. Carpena et al., COMMENT ON CONFINEMENT IN A DOUBLE-BARRIER STRUCTURE IN THE PRESENCE OF AN ELECTRIC-FIELD BY NIMOUR ET-AL, Physics letters. A, 241(1-2), 1998, pp. 131-134
We comment on some of the results and the related conclusions presente
d by Nimour et al. [Phys. Lett. A 716 (1997) 393]. The cause given by
the authors to explain the field dependence of the resonant energies o
f a double barrier structure is not correct. (C) 1998 Elsevier Science
