superlattice (SL) we create quasi-one-dimensional or
quasi-zero-dimensional electronic states. This reduced dimensionality
restricts the range of inelastic scattering processes available to the
conduction electrons, leading to an increase of the inelastic
scattering time and a corresponding decrease of the electrical
conductance. Our study reveals the fundamental link between current
flow and energy dissipation in low-dimensional conductors, which is
relevant to the exploitation of artificial nanowires and quantum dot
SLs for novel applications, including recently proposed thermoelectric
devices.(c) 2006 American Institute of Physics. | | External Publication Status: | published | | Document Type: | Article |
