Multidimensional device architectures for efficient power electronics

Power semiconductor devices are key to delivering high-efficiency energy conversion in power electronics systems, which is critical efforts reduce loss, cut carbon dioxide emissions and create more sustainable technology. Although the use of wide or ultrawide-bandgap materials will be required develop improved devices, multidimensional architectures can also improve performance, regardless underlying material In particular, device architectures—such as superjunction, multi-channel multi-gate technologies—can enable advances speed, efficiency form factor systems. Here we review development for efficient electronics. We explore rationale using different available. consider performance limits, scaling figure merits architectures, identify technological challenges that need addressed realize full potential approach. This Review examines technologies—in exploring architectures.
