This seminar will introduce a new type of bismuth layer-structured ferroelectrics (BLSFs), a suitable candidate for applications in high temperature piezoelectrics and non-volatile FeRAM.
Our Inorganic functional materials have unique electrical, magnetic, acoustic, optical, thermal, mechanical, chemical and biological properties that convert one signal to another, by so-called coupling-effects.
This talk will introduce a new type of bismuth layer-structured ferroelectrics (BLSFs), with characteristics of high Curie temperature, lead-free and fatigue-free ferroelectric properties which make it a suitable candidate for applications in high temperature piezoelectrics and non-volatile FeRAM.
It will discuss nanostructured semiconducting materials by various methods (anodization, sol-gel, VLS) such as nanotubes of TiO2, nano-tabular MoO3, Nb2O5 etc. and finally it will introduce LTCC materials and processing, which are key platforms or techniques for integrated passive electronic devices.
Combining the piezoelectric and sensing materials with LTCC technique, numerous wireless sensors and transducers can be developed in the future, which is a multidisciplinary research field and trend of new materials and integrated devices.
