What happens when silicon transistors can no longer shrink?

The next step in nanotechnology | George Tulevski · 9:36 · Video: TED · Watch at the source

In short: As we reach the physical limits of traditional silicon chips, researchers are looking toward carbon nanotubes to power the next generation of computing.

George Tulevski explores the transition from traditional silicon technology to nanomaterials. While transistors have historically doubled in performance and halved in size nearly every other year, they are approaching a physical ceiling where further shrinking is impossible.

Tulevski's research focuses on developing chemical processes that allow billions of carbon nanotubes to self-assemble into circuit patterns. This method mimics how natural organisms construct complex structures, potentially offering a new pathway for building high-performance, accessible electronics.
