About thirty miles from the main Rethink office, a hive of advanced semiconductor activity is buzzing with activity. We were invited on a trip to explore this cluster of chipmaking wizardry, some of which is utterly foundational to the IoT. Of course, we could only scrape the surface, and for many IoT stakeholders, the intricacies of crystalline structures are utterly removed from their everyday business concerns, but in time, compound semiconductors are going to start cropping up in more and more devices, and powering more and more networks. As it is on our doorstep, it would almost be rude not to check out what was going on. Broadly put, compound semiconductors have very different physical properties, due to their different…
