After a top-down, insightful presentation of the elements of mesoscopic devices and transport theory, a computational technique which treats multiterminal structures of arbitrary geometry and topology is developed. The method relies on the modular assembly of the electronic propagators of subsystems which are inter- or intra-connected providing large flexibility in system setups combined with high computational efficiency. Conductance control is first demonstrated for elongated quantum billiards and arrays thereof where a weak magnetic field tunes the current by phase modulation of interfering lead-coupled states geometrically separated from confined states. Soft-wall potentials are then employed for efficient and robust conductance switching by isolating energy persistent, collimated or magnetically deflected electron paths from Fano resonances. In a multiterminal configuration, the guiding and focusing property of curved boundary sections enables magnetically controlled directional transport with input electron waves flowing exclusively to selected outputs. Together with a comprehensive analysis of characteristic transport features and spatial distributions of scattering states, the results demonstrate the geometrically assisted design of magnetoconductance control elements in the linear response regime. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v927 606 $aSemiconductors 606 $aOptical materials 606 $aElectronic materials 606 $aNanotechnology 606 $aMagnetism 606 $aMagnetic materials 606 $aNanoscale science 606 $aNanoscience 606 $aNanostructures 606 $aSemiconductors$3https://scigraph.springernature.com/ontologies/product-market-codes/P25150 606 $aOptical and Electronic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z12000 606 $aNanotechnology and Microengineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T18000 606 $aMagnetism, Magnetic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/P25129 606 $aNanoscale Science and Technology$3https://scigraph.springernature.com/ontologies/product-market-codes/P25140 615 0$aSemiconductors. 615 0$aOptical materials. 615 0$aElectronic materials. 615 0$aNanotechnology. 615 0$aMagnetism. 615 0$aMagnetic materials. 615 0$aNanoscale science. 615 0$aNanoscience. 615 0$aNanostructures. 615 14$aSemiconductors. 615 24$aOptical and Electronic Materials. 615 24$aNanotechnology and Microengineering. 615 24$aMagnetism, Magnetic Materials. 615 24$aNanoscale Science and Technology. 676 $a530.416 700 $aMorfonios$b Christian V$4aut$4http://id.loc.gov/vocabulary/relators/aut$0959453 702 $aSchmelcher$b Peter$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910250049503321 996 $aControl of Magnetotransport in Quantum Billiards$92174106 997 $aUNINA
