摘要：
In this work, we have calculated magnetotunneling times of electrons in Ga(1-x)Al(x)As-GaAs multiquantum well heterostructures under an external electric field through analytical solutions. Effective-mass equation of electrons in crossed electric and magnetic fields has been analytically solved by means of Confluent Hypergeometric Functions finding the existence of individualized tunneling channels connected with anticrossings in the dispersion relation. It is found that the quantum tunneling time between two coupled quantum wells decreases if B is increased.
