The Silicon atom is about .24 nm. Carbon is about .14 - a bit more than half as big. It looks like there's still some room to make transistors smaller than the sub-10 nm. Not much though. I don't see any solids with a diameter smaller than carbon so that may be it for the traditional binary logic building block.
It's getting close to time to look for something that will give a couple more states from the same size device.
Feynman said that there is plenty of room at the bottom. We are hitting the bottom and it is full of surprises. Graphene, CNT, Nanowires, variation of FinFET will compete for the lower technology nodes for sure.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
