Abstract: Selenium substitution drastically increases the transition temperature of iridium ditelluride (IrTe(2)) to a diamagnetic superstructure from 278 to 560 K. Transmission electron microscopy experiments revealed that this enhancement is accompanied by the evolution of nonsinusoidal structure modulations from q = 1/5(101) to q = 1/6(101) types. These comprehensive results are consistent with the concept of the destabilization of polymeric Te-Te bonds at the transition, the temperature of which is increased by chemical and hydrostatic pressure and by the substitution of Te with the more electronegative Se. This temperature-induced depolymerization transition in IrTe(2) is unique in crystalline inorganic solids.

TL;DR: In this paper, single-crystal X-ray diffraction was employed to study the structural-electronic phase transition of IrTe2 at approximately 270 K. The low-temperature structure was found to be a triclinic (space group \(P\bar{1})) characterized by the partial formation of Ir2 dimers in the triangular lattice, resulting in a structural modulation with a wave vector of q = (1/5, 0, − 1/5).

TL;DR: In this article, a superconducting dome is identified well inside the parent stripe charge ordering phase in the thickness-dependent phase diagram in IrTe2 nanoflakes, showing that the inherent instabilities of the parent stripes phase are sufficient to induce superconductivity without its complete or partial melting.

TL;DR: Topological superconductors are new states of quantum matter which cannot be adiabatically connected to conventional insulators and semiconductors and are characterized by a full insulating gap in the bulk and gapless edge or surface states which are protected by time reversal symmetry.
Single-layer MoS2 transistors
TL;DR: Because monolayer MoS(2) has a direct bandgap, it can be used to construct interband tunnel FETs, which offer lower power consumption than classical transistors, and could also complement graphene in applications that require thin transparent semiconductors, such as optoelectronics and energy harvesting.
