Abstract: Abstract Unconventionally high amount of atomic vacancies up to more than 10% are known to form in Ge-Sb-Te crystals upon rapid crystallization from the amorphous phase. Upon thermal annealing, an ordering process of these atomic… read more here.

Abstract: We demonstrate that Na+/vacancy disordering of P2-type layered cathodes ensures both fast Na mobility and a low Na diffusion barrier. As one of the most fascinating cathode candidates for Na-ion batteries (NIBs), P2-type Na layered… read more here.
