Morfonios, Peter Schmelcher is a physics book focused on Devices \u0026amp; Sensors. Best for students, educators, and scientifically curious readers.\u003c\/p\u003e\n\u003cp\u003eIn this book the coherent quantum transport of electrons through two-dimensional mesoscopic structures is explored in dependence of the interplay between the confining geometry and the impact of applied magnetic fields, aiming at conductance controllability. 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.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Default Title","offer_id":46421866578119,"sku":"1-99-537-000137","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/9575\/6487\/files\/9783319398310.jpg?v=1776382552","url":"https:\/\/snowflakeskies.com\/products\/control-of-magnetotransport-in-quantum-billiards-theory-computation-and-applications-2017","provider":"Snowflake Skies","version":"1.0","type":"link"}
