Collapse of layer dimerization in the photo-induced hidden state of 1T-TaS2Two-dimensional materialsElectronic properties and materialsPhase transitions and critical phenomenaThe layered host structure of 1T-TaS comprises S-Ta-S layers (Spacegroup: 1). The structural key feature of the C and NCC...
normalized toJ. Close to the AF state, thed + idstate and the nodald-wave state strongly compete, leading to a pocket of stability for thed + idstate. Dashed lines show possibleJ2–Kmapping of the parametersg1andg2. The purple arrow shows a possible parameter path for 1T-TaS...
A prototypical quasi-2D metallic compound, 1T-TaS2 has been extensively studied due to an intricate interplay between a Mott-insulating ground state and a charge-density-wave order. In the low-temperature phase, 12 out of 13 Ta4+ 5d-electrons form molecular orbitals in hexagonal star-of-David...
The crystal structure of dibromo-2,5-dimethylpyrazinenickel(II) (NiBr2(CH3)2N2C4H 2) Crystals are monoclinic, space group C2/m, a = 9.09, b = 8.20, c = 6.52 ., β = 108° 36′, two formula units per unit cell. The structure consists of infinite chains of (2,5-dmp)NiBr2 alo...
