Abstract

An interinfluence effect of neighboring metal-ferroelectric-semiconductor (MFS) membrane structures synthesized on the common insulating layer was found. Different voltages applied to the field electrodes of the two adjacent structures produce, in the free-of-substrate ferroelectric film surrounding the elements, common inhomogeneous deformation and polarization fields through which the interinfluence occurs. The interinfluence phenomenon is strong enough: the HF capacity of the MFS object increases by up to 3 times after applying an up to 5 V bias to the adjacent similar element for which the C–V characteristics are measured. The interinfluence phenomenon was observed in thin-substrate structures whose geometry was far from that of perfect membranes: the thickness of the ferroelectric layer was 66 times smaller than that of the semiconductor. Interinfluence shows itself at each hysteresis loop of the MFS structure C–V characteristic in the transition section between the two plateaus. The capacity of the test specimen increases with the absolute bias value and depends but slightly on the bias polarity applied to the adjacent object.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
