Additionally, the possibility to control the 2D carrier density via gate voltages through the electric field-effect offers a great advantage of external manipulation of the system. With the optimization of lithography on a nanometre scale, gated 2D systems in semiconductor heterostructures are currently intensively studied as platforms for few to single-carrier devices. In this context, a precise control of the heterostructure layout including the doping, as well as an understanding of charge reconfiguration effects within the device, are important challenges. This thesis, addresses the heterostructure optimization and focuses on a precise field-effect control of Schottky top-gated modulation doped Si\/SiGe heterostructures. For the optimization of the heterostructure design, several parameters which affect the strain, the band offset and the doping degree in Si\/SiGe two-dimensional electron systems are precisely studied. In parallel, the field-effect influence on Si\/SiGe heterostructures is used to identify the origin of disorder and possible sources of charge noise. In this connection, finally a modified charge transfer model including a polarizability of neutral phosphorous atoms inside the doping layer is developed.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Michael Schmalzbauer\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3868451234\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783868451238\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Universitatsverlag Regensburg\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/22\/2015\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 160\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.90lbs","brand":"Michael Schmalzbauer","offers":[{"title":"Paperback","offer_id":48450145878271,"sku":"9783868451238","price":39.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_cd7e0a0f-561b-49f4-8620-60d1cb84f193.jpg?v=1777266408","url":"https:\/\/www.whiterainbookhouse.com\/products\/heterostructure-design-of-sisige-two-dimensional-michael-schmalzbauer-9783868451238","provider":"WR Book House","version":"1.0","type":"link"}
