This book delves into the use of ferroelectric materials in information technology by developing prototype devices from Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) single crystals. It details the construction of an optothermal field-effect transistor (FET) on the PMN-26PT crystal, utilizing a MoS2 monolayer as the channel semiconductor. This integration of the pyroelectric effect with 2D materials' interface engineering offers a promising approach for advancing FET technology. Additionally, an ultra-broadband photodetector, capable of operating from UV to THz frequencies, was monolithically integrated into a [111]-oriented PMN-28PT single crystal, employing silver nanowires in the transparent top electrode. This photodetector achieved a remarkable operational frequency of up to 3 kHz, significantly surpassing traditional pyroelectric photodetectors. The book also presents a self-powered integrated module that combines a triboelectric nanogenerator with a ferroelectric FET, enabling efficient information writing in memory systems using mechanical energy, thus addressing power consumption challenges in ferroelectric nonvolatile memories. Overall, it expands the applications of ferroelectric single crystals beyond piezoelectric devices, setting the stage for future innovations.
