Scientists have created a microchip with negative energy, which is 170 times more powerful than analogs

Scientists from Laboratory named after Lawrence e Berkeley and University of California have created microcapacitors with negative capacitance, which increase power by 170 times. The chips are made of thin films of hafnium oxide and zirconium oxide and use materials that are already used in production of advanced electronics.

«The uniqueness of these microcapacitors lies in the ability to accumulate more energy due to the use of materials with negative capacitance», —

Capacitors are the main components of electrical circuits that store energy in an electric field between two metal plates separated by a dielectric. Traditional capacitors have a low energy density, which limited their use in high-power devices. The researchers overcame these limitations by developing HfO2-ZrO2 thin films with a negative capacitance effect, achieving record energy density and power.

The films were integrated into a three-dimensional structures of microcapacitors and achieved an energy density nine times higher and a power density 170 times higher compared to the best electrostatic capacitors. This opens up new opportunities for miniaturization of energy storage systems in microdevices, Internet of Things devices ( IoT), peripheral computing systems and artificial intelligence processors.
