Electronic Devices Could get Even Smaller Thanks to New Micro-Capacitors
Scientists from Berkeley Lab and UC Berkeley have discovered a way to make electronic devices smaller and more efficient thanks to new microcapacitor technology. This new technology would allow the microchips within devices to store energy, and thus the energy losses that occur as energy moves throughout the devices’ different parts would be minimized. The researchers used thin films of hafnium oxide and zirconium oxide to make the microcapacitors, which achieved record-high energy and power densities. UC Berkeley professor Sayeef Salahuddin said “The energy and power density we got are much higher than we expected." He further noted, "We've been developing negative capacitance materials for many years, but these results were quite surprising." Technologies that could directly benefit from these new microcapacitors include smartphones, sensors, computers, and several others. co-author of the study Suraj Cheema said that “"With this technology, we can finally start to realize energy storage and power delivery seamlessly integrated on-chip in very small sizes," and that  "It can open up a new realm of energy technologies for microelectronics."
