晶格空位在晶格里由于缺少一个原子、一个离子或一个分子造成晶格空位。
A crystal defect caused by the absence of an atom, an ion, or a molecule in a crystal lattice.
同时理论方法还表明，空位缺陷对薄膜热导率的巨大影响归因于晶格应力的存在使点缺陷也发生散射作用的结果。
In addition, theoretical analysis indicates that the reduction in the lattice thermal conductivity with vacancy defects can be explained by the enhanced point-defect scattering due to lattice strain.
