发现了控制反钙钛矿氮化锰零热膨胀(ZTE)行为的通用机制。调节其晶格位置处的锰占据量会导致热膨胀行为发生巨大变化。通过对材料进行纳米结构处理,可以减少锰位点的占用,从而产生“巨型”ZTE 的形式。
A universal mechanism that controls the zero thermal expansion (ZTE) behavior of the antiperovskite manganese nitrides is discovered. Modulating the Mn occupancy at its lattice sites leads to a drastic change in the thermal expansion behavior. The Mn site occupancy can be reduced by nanostructuring the material, generating a form of "giant" ZTE.
