A third smaller than conventional devices, they might be used in ultra-compact wireless communication systems for applications in IoT, sensing, and energy storage/ transfer. This also highlights a practical application for graphene beyond interconnects. The researchers are looking to make their fabrication processes compatible with BEOL CMOS technology.

SONIC Prof. Kaustav Banerjee (UCSB) led a team that has reinvented this fundamental passive device, demonstrating the first high-performance inductors from intercalated multi-layer graphene (MLG). The inductors work in the 10-50 GHz range thanks to the completely new mechanism of kinetic inductance, which differs from the magnetic inductance in conventional devices. The new inductors, have small form-factors and high inductance values, of around 1-2 nanoHenry.

This also highlights a practical application for graphene beyond interconnects. The researchers are looking to make their fabrication processes compatible with BEOL CMOS technology.
