This week's guest is Eric Vogel, a Professor of Materials Science and Engineering at Georgia Tech and the Deputy Director of the Institute for Electronics and Nanotechnology (IEN). We talk transistors — the original nanotechnology — and what these super tiny switches can teach us about future nanotechnologies. We discuss why we keep shrinking transistor size, the manufacturing challenges associated with this "scaling," and what looks like the end of the road for conventional integrated circuits. Don't miss the after-show where we ask: what if we move to a new integrated circuit architecture? The answer is a doozy. (Recorded on February 16, 2016)
