PCPBT: Problem Assignment for Asymmetric Barriers
24 Jun 2009 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This example demonstrates to the students that for non-symmetric barriers which arise due to the imperfection of the molecular beam epitaxy process there is a reduction in the transmission coefficient and therefore current.
