Dr. Alexey Bezryadin, with his research group, has developed a dielectric capacitor that provides 200 J/g of storage density. By injecting and trapping charges within a thin dielectric layer, a Coulomb barrier is created that prevents leakage currents that cause capacitors to discharge more quickly. Initial applications for the technology are in cold electronics, which could include quantum computing, space technologies, infrared cameras, or MRI machines.
