DOI: 10.1002/aenm.202000363
Abstract: The relatively low capacity and capacity fade of spinel LiMn2O4 (LMO) limit its application as a cathode material for lithium‐ion batteries. Extending the potential window of LMO below 3 V to access double capacity would… read more here.

DOI: 10.1088/1361-6463/abead5
Abstract: High-quality epitaxial LaMnO3 films have been grown on (001)-oriented LaAlO3 substrates at different substrate temperatures by pulsed laser deposition. The layer-by-layer growth is indicated by oscillations of reflection high-energy electron diffraction. Raman spectra together with… read more here.

DOI: 10.1103/physrevb.107.134431
Abstract: The Jahn-Teller distortion and the resulting orbital order usually cause some fascinating correlated electronic behaviors, and generally lead to antiferromagnetism in perovskite bulks. Here we demonstrate that the Jahn-Teller distortion present in the perovskite fluoride… read more here.
