Abstract:

THIS PROPOSAL DISCUSSES A PROGRAM FOR UTILIZING AND EXPANDING AN INNOVATIVE QUANTUM BASED MULTI-PARTICLE SELF-CONSISTENT ALGORITHM FOR SOLVING THE EQUATION OF MOTION OF THE DENSITY MATRIX TO EXPLORE NEW DEVICE PHENOMENA. THE ALGORITHM HAS BEEN DEVELOPED AT SRA AND OFFERS FOR THE FIRST TIME THE POSSIBILITY OF NUMERICALLY EXAMINING THE FUNDAMENTAL ISSUES GERMANE TO THE TIME DEPENDENT MIXING OF QUASI-BOUND STATES IN A QUANTUM WELL DIODE, AND THE ANTICIPATED DEVICE APPLICATIONS. THE PROPOSAL ILLUSTRATES THIS TIME DEPENDENT MIXING FOR A SIMPLE POTENTIAL WELL OF FINITE DEPTH. THE INNOVATIVE USE OF THE DENSITY MATRIX FORMULATION INCORPORATES THE NONLOCALITY OF THE BOUNDARY CONDITIONS WHICH IN THIS FORMULATION, WITH THE EXCEPTION OF TWO POINTS, ARE OFF-DIAGONAL ELEMENTS. THE PROPOSED PROGRAM WILL FOCUS ON OBTAINING SELF-CONSISTENT SOLUTIONS FOR QUASI-BOUND STATE MIXING ARISING FROM THE APPLICATION OF A HIGH FREQUENCY SIGNAL, IMPOSED UPON A RECENTLY REPORTED PSEUDOMORPHIC IN.(53)GA.(47)AS/ALAS/INAS DOUBLE BARRIER RESONANT TUNNELING DIODE, WHICH HAS DISPLAYED PEAK-TO VALLEY CURRENT RATIOS OF 30.
