Hence it could be shown that the solution-crystallized material (α form) underwent a solid–solid phase transition to the β modification at a temperature corresponding to the observed endotherm. This β form then converted to a more stable modification (β′ form) which represented a ...
Topotactic transition of Pb_(0.99)Bi~(0.01)I_2 into CH_3NH_3Pb_(0.99)Bi_(0.01)I_3 on TiO_2 for high-performance visible light perovskite photodetector Topotactic transition of Pb_(0.99)Bi~(0.01)I_2 into CH_3NH_3Pb_(0.99)Bi_(0.01)I_3 on TiO_2 for high-performance visible light...
SrFeOxtopotactic phase transformationResistive switching (RS) memory has stayed at the forefront of next-generation nonvolatile memory technologies. Recently, a novel class of transition metal oxides (TMOs), which exhibit reversible topotactic phase transformation between insulating brownmillerite (BM) ...
A small oxygen k-edge transition (25 ± 2%) in addition to carbon k-edge was also observed from the EELS spectrum of NWs. No oxygen was detected in the MWCNT spectrum, while strong oxygen k-edge (86 ± 3%, Supplementary Fig. 3d) was obtained from the amorphous structure after...
Mechanism of the transition from orthorhombic to tetragonal YBa 2 Cu 3 O 7− x . Investigation of a reversible topotactic reaction in the electron microscopeMechanism of the transition from orthorhombic to tetragonal YBa 2 Cu 3 O 7− x . Investigation of a reversible topotactic reaction in ...
Mo 3S 4 and Mo 3Se 4 were found to undergo topotactic electron-ion exchange reactions at ambient temperatures in aqueous and non-aqueous electrolytes containing transition or main group cations. The products of cathodic reduction are ternary phases A xMo 3X 4. Mobilities of the exchangeable ...
In contrast, cuprates, nickelates, and, to a lesser extent, iron pnictides are strongly correlated electron systems with a large Coulomb interaction between electrons because of their narrow transition metal orbitals. Their 𝑇𝑐Tc is too high for BCS theory [37,38], and the origin of ...
