In the past decades,BiFeO3 (BFO) has attracted tremendous investigations due to its superior mutliferoicities at room temperature.It is reported that its physical properties are very sensitive to poin
We report a systematic first-principles study on the ferroelectric behavior of ultrathin three-component ferroelectric films,e.g.,CaTiO3-BaTiO3-SrTiO3,sandwiched between electrodes.Using first-princip
La2Si2O7 ceramics prepared by reactive sintering process (RS) and conventional solid state reaction (SS) were investigated in the study.We mainly compared the influences of different processes on phas
There is an urgent need for developing high performance rechargeable lithium-ions batteries (LIBs) with high charge/discharge rates and high energy capacity to back up new high power tools.1,2 LIBs wi
