Abstract Solid‐state Li batteries using Na + superionic conductor type solid electrolyte attracts wide interest because of its safety and high theoretical energy density. The NASCION LAGP (Li 1. 5 Al 0.5 Ge P 3 O 12 ) shows favorable conductivity as well good mechanical strength to prevent dendrite penetration. However, the instability with metal remains a great challenge. In this work, an amorphous thin film is sputtered on surface, which can not only suppress reduction reaction 4+ Li, but...

In terms of interlayer trions, electronic excitations in van der Waals heterostructures (vdWHs) can be classified into Type I (i.e., two identical charges the same layer) and II different layers). trions are investigated theoretically experimentally. By contrast, remain elusive vdWHs, due to inadequate free charges, unsuitable band alignment, reduced Coulomb interactions, poor interface quality, etc. Here, first observation is reported by exploring alignments choosing an atomically thin...
