All our computers and digital devices are made from semiconductors. But what is so special about them? Why do we use them? In this video let's explore, what it is about semiconductors, that allows us to create all these awesome computing devices.  Mahesh Shenoy video https://cdn.kastatic.org/googleusercontent/YWhn291XPV4IDtdw5HOGv5cP3AyspmV58VYtorTgxyo73gC3YFFRZuoTk0KFfhLsPF5DKK5QNHXJ1LKTE6YHdzY Intro to semiconductors Why are we obsessed with semiconductors?
