Observation of the surface hybridization gap in the electrical transport properties of the ultrathin topological insulator (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$

Feike van Veen, Sofie Kölling, Stijn R. de Wit +4

We study the three-dimensional topological insulator (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ in its ultrathin limit i.e. when the thickness is of the same order as the surface state pen…

Signature of current-induced nuclear spin polarization in (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$

Sofie Kölling, İnanç Adagideli, Alexander Brinkman

In systems with spin-momentum locking, such as the surface states of three-dimensional topological insulators, a charge current is spin-polarized and spin-flip interactions between…

Non-Ohmic behavior in (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ by Joule heating

Sofie Kölling, Daan H. Wielens, İnanç Adagideli +1

A prerequisite to using the net spin polarization generated by a source-drain bias in three-dimensional topological insulators for spintronic applications, is understanding how suc…

Gate electrode-induced nonreciprocal resistance in topological insulators

Sofie Kölling, Florian R. Westerhof, Alexander Brinkman

A common method of controlling the chemical potential in topological insulators is applying a gate electrode. Simultaneously applying high source-drain bias currents can lead to pa…

Entropy Driven Inductive Response of Topological Insulators

A. Mert Bozkurt, Sofie Kölling, Alexander Brinkman +1

3D topological insulators are characterized by an insulating bulk and extended surface states exhibiting a helical spin texture. In this work, we investigate the hyperfine interact…
