Topological insulator single-electron transistors for charge sensing applications

Omargeldi Atanov, Junya Feng, Jens Brede +2

We present topological insulator (TI)-based single-electron transistors (SETs) as magnetic-field-compatible charge sensing devices that are easily integrable with TI-superconductor…

Ex Situ Fabrication of Superconducting Nanostructures for Low-Temperature STM

Adrian Greichgauer, Roozbeh Yazdanpanah, Alexey Taskin +3

Nanofabrication of topological insulator (TI) devices is essential for accessing edge and interface states, but conventional lithography and etching compromise the atomically clean…

Quasiparticle interference on the surface of Bi $_{2}$ Se $_{3}$ terminated (PbSe) $_{5}$ (Bi $_{2}$ Se $_{3}$ ) $_{6}$

Mahasweta Bagchi, Philipp Rüßmann, Gustav Bihlmayer +3

Among the family of topological superconductors derived from {\BiSe}, $Cu_{x} (PbSe)_{5} (Bi_{2} Se_{3})_{6}$ is unique in its surface termination of…

Characterizing the chemical potential disorder in the topological insulator (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ thin films

Jens Brede, Mahasweta Bagchi, Adrian Greichgauer +6

We use scanning tunneling microscopy and spectroscopy under ultra-high vacuum and down to 1.7 K to study the local variations of the chemical potential on the surface of the topolo…
