Maintaining the morphology of electrode materials with high invertibility contributes to prolonged cyclic stability battery systems. However, majority tend degrade during charge-discharge process owing inevitable increase in entropy. Herein, a self-healing strategy is designed promote rejuvenation Prussian blue analogue (PBA) cathodes by cobalt doping. Experimental characterization and theoretical calculations demonstrate that trace amount can decelerate crystallization restore cracked areas...
Vanadium dioxide (VO2) exhibits an insulator-to-metal transition accompanied by a structural near room temperature. This can be triggered ultrafast laser pulse. Exotic transient states, such as metallic state without transition, were also proposed. These unique characteristics let VO2 have great potential in thermal switchable devices and photonic applications. Although efforts been made, the atomic pathway during photoinduced phase is still not clear. Here, we synthesize freestanding...
Abstract KAg 3 Te 2 with a layered crystal structure has been predicted to be possible topological insulator. Through electrical transport measurements, we revealed its semiconducting behavior narrow band gap of ~0.4 eV and p-type character. The infrared transmission spectra single crystals yielded an optical ~0.3 eV. Angle-resolved photoemission spectroscopy reveals bulk energy at the Brillouin zone center, no observable surface state, suggesting that is trivial narrow-gap semiconductor....
A vast landscape of topological phases matter with emergent quasiparticles has been explored in the past two decades, but majority them are 2D or 3D essence and far fewer 1D counterparts known to exist.

Abstract By combining angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations, we have studied the electronic band structure of a topological material candidate TaPdTe 5 .Two inverted bulk gaps determined through parity analysis were observed in near Fermi level, which causes appearance topologically protected surface states on (010) surface. Beside state, also strong resonance state. The hybridization between state changes quasi-one-dimensional like sheets into...
