The earth's crust and outer space are rich sources of technologically relevant materials which have found application in a wide range of fields. Well-established examples are diamond, one of the hardest known materials, or graphite as a suitable precursor of graphene. The ongoing drive to discover novel materials useful for (opto)electronic applications has recently drawn strong attention to topological insulators. Here, we report that Kawazulite, a mineral with the approximate composition Bi2… Expand
Dimensional crossover in the quantum transport behaviour of the natural topological insulator Aleksite
TLDR
The size-dependent electronic properties of nanostructures made of the lead-containing mineral Aleksite, a naturally occurring topological insulator, are explored, finding a 1D weak antilocalization effect along with 1D universal conductance fluctuations emerges, which transforms into 2D behavior for larger ribbon widths.

Prediction of a two-dimensional organic topological insulator.
TLDR
This work identifies a recently experimentally made 2D organometallic framework, consisting of π-conjugated nickel-bis-dithiolene with a chemical formula Ni3C12S12, which exhibits nontrivial topological states in both a Dirac band and a flat band, therefore confirming the existence of OTI. Expand

Topological insulators represent a new quantum state of matter which is characterized by peculiar edge or surface states that show up due to a topological character of the bulk wave functions. ThisExpand

Ambipolar field effect in the ternary topological insulator (Bi(x)Sb(1-x))2Te3 by composition tuning.
TLDR
By tuning the ratio of bismuth to antimony, this work is able to reduce the bulk carrier density by over two orders of magnitude, while maintaining the topological insulator properties, and observes a clear ambipolar gating effect in (Bi(x)Sb(1-x))2Te3 nanoplate field-effect transistor devices, similar to that observed in graphene field- effect transistor devices.

A search model for topological insulators with high-throughput robustness descriptors.
TLDR
By defining a reliable and accessible descriptor, which represents the topological robustness or feasibility of the candidate, and by searching the quantum materials repository aflowlib.org, 28 TIs are automatically discovered, including peculiar ternary halides, Cs{Sn,Pb,Ge}{Cl,Br,I}(3), which could have been hardly anticipated without high-throughput means.

TLDR
Experimental evidence of the UCFs of the two-dimensional surface state in the bulk insulating Bi2Te2Se microflakes is reported and the electron-phonon interaction is addressed as a secondary source of the surface state dephasing based on the temperature-dependent scaling behavior. Expand
Growth of high-mobility Bi2Te2Se nanoplatelets on hBN sheets by van der Waals epitaxy.
TLDR
The surface state carrier mobility of nanoplatelets on hBN is increased by a factor of about 3 compared to platelets on conventional Si/SiO(x) substrates, which enables the observation of well-developed Shubnikov-de Haas oscillations. Expand
Topological insulators in Bi2Se3, Bi2Te3 and Sb2Te3 with a single Dirac cone on the surface
Topological insulators are new states of quantum matter in which surface states residing in the bulk insulating gap of such systems are protected by time-reversal symmetry. The study of such statesExpand
Impurity effect on weak antilocalization in the topological insulator Bi2Te3.
TLDR
The data demonstrate that the observed WAL is robust against deposition of nonmagnetic Au impurities on the surface of the thin films, but it is quenched by the deposition of magnetic Fe impurities which destroy the π Berry phase of the topological surface states. Expand
