A group of researchers led by Dr. Takayoshi Sasaki and Dr. Minoru Osada of MANA of NIMS, succeeded in developing the world’s smallest high-performance capacitor by assembling two types of oxide nanosheets, – a conductive oxide nanosheet and a dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. oxide nanosheet – into a sandwich structure, in the manner of LEGO block game.

These nanosheets can be obtained in the form of a mono-dispersed colloid suspension as shown in the photos.
A capacitor is an electronic component used in various electronic appliances, such as smartphones and personal computers. The type of capacitor currently in common use is a multilayer ceramic capacitor (MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance.) formed by laminating alternating layers of dielectricThe insulating material between the plates of the capacitor.

This type of capacitor has been reduced in size and improved in performance through what is generally called a “top-down” approach, by such means as creating thinner or integrated elements through the use of the advanced particle processing technology or thin film technology.
Amid the recent trend toward making ever smaller, lighter and more sophisticated mobile devices, there is a call for further MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance. size reduction and sophistication. However, the existing technology has already reached its limits both in terms of materials and processes, and a dramatic increase in performance and technological innovation by means of new materials and processes is strongly demanded.
By applying a “bottom up” rather than “top down” approach, in contrast to the conventional development of capacitor elements, the research group developed a new process with inorganic nanosheets – two dimensional nanocrystals with molecular thickness – for use in a novel element production. They thereby succeeded in creating the world’s smallest high-performance capacitor element.
