Surface State Transport and Ambipolar Electric Field Effect in Bi2Se3 Nanodevices
Hadar Steinberg, Dillon R. Gardner, Young S. Lee +1
Electronic transport experiments involving the topologically protected states found at the surface of Bi2Se3 and other topological insulators require fine control over carrier dens…
Electronic Transport in Dual-gated Bilayer Graphene at Large Displacement Fields
Thiti Taychatanapat, Pablo Jarillo-Herrero
We study the electronic transport properties of dual-gated bilayer graphene devices. We focus on the regime of low temperatures and high electric displacement fields, where we obse…
Ambipolar Electric Field Effect in Metallic Bi2Se3
Hadar Steinberg, Dillon R. Gardner, Young S. Lee +1
Topological insulators (TIs) constitute a new class of materials with unique properties resulting from the relativistic-like character and topological protection of their surface s…
