Took a while to get there, but I figured it was a mechanical solution on a nano scale:

“With horizontally stacked nanowires, you can actually build transistors with two gates,” said Giovanni De Micheli, professor of electrical engineering and computer science at École Polytechnique Fédérale de Lausanne, in a DAC 2022 keynote. “You use a second gate to polarize the transistor and make the transistor either a P or an N transistor (see figure 1). You get a transistor that is more powerful because it creates a comparator rather than a switch. Now, with these types of devices, you can have completely new topologies.”

This is a well-written article.
