Scientists at Lawrence Berkeley National Laboratory and UC Berkeley have created micro-capacitors with record-breaking energy and power densities using hafnium and zirconium oxide thin films. These capacitors achieve nine times higher energy density and 170 times higher power density than current technologies, enabling more efficient on-chip energy storage for advanced electronics. This breakthrough could revolutionize miniaturized devices like IoT sensors and AI processors.

For the first time, researchers have imaged negative capacitance at the microscopic level, revealing how it could enhance energy efficiency in electronics. Led by UC Berkeley, the study published in Nature shows that negative capacitance, where voltage and charge change oppositely, can improve voltage and reduce power needs. This breakthrough, confirmed through advanced imaging and modeling, could significantly impact transistors, batteries, and other electronic devices.

Researchers at DOE's Argonne National Laboratory have created a permanent static negative capacitor, a concept once thought impossible. This new device, detailed in Communications Physics, operates steadily and reversibly, improving energy efficiency by enhancing local voltage in circuits. Using ferroelectric materials, the negative capacitor works in tandem with a positive capacitor to optimize power use. The research was supported by the DOE and HORIZON 2020.

The researchers deduced design optimisation rules for the combination of materials they used. “These rules are expected also to be useful for optimizing other multilayer systems and are therefore very relevant for further increasing the energy storage density of capacitors”, they write in their publication. This paves the way for even better capacitors.
