This book explores the applications of ferroelectric materials in
information technology by developing several prototype devices
based on Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) single crystals. It
describes how an optothermal field-effect transistor (FET) was
constructed on the PMN-26PT single crystal, using a MoS2 monolayer
as the channel semiconductor material. This fusion of pyroelectric
effect and the interface engineering of 2D materials provides an
effective strategy for the 'photon revolution' of FET. An
ultra-broadband photodetector (UV ~ THz) was monolithically
integrated into a [111]-oriented PMN-28PT single crystal by using
silver nanowires in the transparent top electrode. The
photodetector showed a dramatic improvement in operation frequency
up to 3 kHz: an order of magnitude higher than that of traditional
pyroelectric photodetectors. A self-powered integrated module was
demonstrated through the combination of a triboelectric
nanogenerator and a ferroelectric FET. The stored information can
easily be written in the memory system using mechanical energy,
solving the power consumption problem with regard to information
writing in ferroelectric nonvolatile memories. This book extends
the applications of ferroelectric single crystals into areas other
than piezoelectric devices, paving the way for exciting future
developments.
