FINITE-FIELDS AND INTERVALLEY SCATTERING IN A RESONANT-TUNNELING QUANTUM-WIRE AND DOT DOUBLE-BARRIER STRUCTURE USING A MULTIBAND MICROSCOPIC LAYER METHOD

We present a multiband calculation of resonant electron tunneling thro ugh quantum wires and dots consisting of a double barrier structure. A layered version of the empirical pseudopotential method is used with the addition of hard wall boundary conditions to model a structured si ngle layer (wires) and a structural individual wire (dots). Our result s show clearly the importance of non-parabolicity and intervalley mixi ng in these reduced dimensional structures. The inclusion of electric fields allows for the investigation of Stark effects in wires and dots .
