2. ABACUS: Test for PCPBT Lab

   05 Aug 2010 | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

   The objective of this test is to give an idea to a self-learning students or to instructors in the case this test is used in a classroom the level of understanding of this topic when students have gone through the learning material, worked exercises and have completed the assignments and the...

3. PCPBT Manual

   This is a manual for the Piece-Wise Constant Potential Barrier Tool.

4. 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.

5. PCPBT Exercise - Symmetric Barriers

   23 Jun 2009 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

   This exercise explores the nature of the quasi-bound states in a symmetric double barrier structure and how the broadening and the position of the quasi-bound states varies with the hidth and the height of the barriers.

6. Tunneling Through Triangular Barrier: an Exercise for PCPBT

   out of 5 stars 

   23 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

   This exercise teaches the users that a very good result can be obtained when the triangular barrier is approximated with 11 segment piece-wise constant potential barrier steps. www.eas.asu.edu/~vasilesk NSF
