In this work, the p-doped topological insulators SnSb(2)Te(4), SnBi(0,1)Sb(1,9)Te(4), SnBi(0,2)Sb(1,8)Te(4) and GeSb(2)Te(4) are investigated, the topological surface state withing the band gap is determined and their spin polarization is verified with circular dichroism. The possibility of a selective excitation of the spin-polarized states, and with that a spin-current, is tested with circular polarized pump pulses and discussed in the context of the ultrafast dynamics of the systems as well as the current developments in literature.<\/p>","protected":false},"excerpt":{"rendered":"
In dieser Arbeit werden die intrinsisch p-dotierten topologischen Isolatoren SnSb(2)Te(4), SnBi(0,1)Sb(1,9)Te(4), SnBi(0,2)Sb(1,8)Te(4) und GeSb(2)Te(4) untersucht, deren topologische Oberfl\u00e4chenzust\u00e4nde innerhalb der Bandl\u00fccke bestimmt, und mit Zirkulardichroismus-Messungen auf ihre Spinpolarisation getestet. Der Machbarkeit einer selektiven Anregung spinpolarisierter Zust\u00e4nde, und damit der Erzeugung eines Spinstromes, wird mit zirkular polarisierten Anregungspulsen nachgegangen und im Kontext der ultraschnellen Dynamik der […]<\/p>\n","protected":false},"featured_media":2643,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[60],"product_tag":[],"class_list":{"0":"post-1880","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-fau-studies-mathematics-physics","7":"has-post-title","8":"has-post-date","9":"has-post-category","10":"has-post-tag","11":"has-post-comment","12":"has-post-author","13":"","15":"first","16":"instock","17":"taxable","18":"shipping-taxable","19":"purchasable","20":"product-type-simple"},"acf":{"autor":"Otto, Sebastian","orcid":"","ror":"","herausgeber":"","orcid_hrsg":"","rorhrsg":"","bearbeiter":"","sonstige_beteiligte_personen":"","untertitel":"","zusatz":"","jahr":"2021","zeitschrift":"","serie":"","serie_name":"","serie_band":"","serie_jahr":"","serie_titel_band":"","vortrage":"","issn":"","isbn":"","isbn13":"978-3-96147-396-0","seiten":"iv, 139","sonstiges":"","band":18,"auflage":"","opus":"","dspace":"15943","e-isbn_pdf":"978-3-96147-397-7","doi":"https:\/\/doi.org\/10.25593\/978-3-96147-397-7","epub":"","e-isbn_epub":"","doi_epub":"","html":"","e-isbn_html":"","doi_html":"","e-isbn_reader":"","doi_reader":"","digibib":"","urn":"urn:nbn:de:bvb:29-opus4-159434","supplementary_material":"","sprache":["Deutsch"],"ausgabe":"Softcover","suche":" 9783961473960 9783961473977 ","lizenz":"BY-NC-4","bemerkung":""},"builder_content":"","_links":{"self":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product\/1880","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/comments?post=1880"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media\/2643"}],"wp:attachment":[{"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/media?parent=1880"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_brand?post=1880"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_cat?post=1880"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.university-press.fau.de\/en\/wp-json\/wp\/v2\/product_tag?post=1880"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
