Retraction: Exploring multiband tunneling for uncoupled particles: A polynomial view (J. Appl. Phys. (2017) 122 (184301) DOI: 10.1063/1.4996182)

The authors have agreed to retract the referenced paper¹due to significant overlap with other publications.^2-5The authors recognized that they have misrepresented a published theoretical model as if they had found it. The theoretical treatment of multiband multicomponent systems presented in Sec. II was reproduced from a preprint,²which was later published.³The non-commutative polynomial recurrence relation and the closed formu-las for tunneling time through superlattices were also reproduced from previously published material.^4,5The authors deeply regret their actions and sincerely apologize. They recognize that their misrepresentation does not comply with the ethical standards of AIP Publishing and of Journal of Applied Physics.
