ملخص: Is it possible to confine positrons in some region of the so-called semiconducting superlattice, in the absence of any vacancies or defects, as is done with electrons? In other words, can positrons be useful for probing such structures? In this paper, our aim is to answer these questions. To that end, we calculate the bandstructures and the charge densities of positrons in these systems. Two possible superlattice configurations are considered. Interesting and new results are obtained. In the light of the present work, it is shown that the positron confinement is possible, and its utilization as a direct probing tool for superlattices is proposed.
