I could see it with some sort of CVD, but the problem would be keeping a crystal structure in the build. Unless you're hysically pushing atoms around, there's no guarantee to keep a planer, monocrystaline surface, and that's required for the semiconductor to work.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
