Mesopores induced zero thermal expansion in single-crystal ferroelectrics

Zero thermal expansion materials—often composites of negative and positive coefficient materials—are needed for applications that see large temperature changes. Here, the authors demonstrate that polarization around pores in single-phase mesoporous lead titanate can be used to tune thermal expansion...

Description
Summary:Zero thermal expansion materials—often composites of negative and positive coefficient materials—are needed for applications that see large temperature changes. Here, the authors demonstrate that polarization around pores in single-phase mesoporous lead titanate can be used to tune thermal expansion to near zero.
