Abstract
An extension of the generalized scattering matrix (GSM) technique is formulated to compute the GSM of nonuniform quantum waveguide structures with two-dimensional quantum confinement of electronic states. Low-temperature I-V characteristics for a double constriction are presented, exhibiting a region of negative differential resistance (NDR). A simple design procedure for increasing the temperature range with achievable NDR is introduced.
