Thanks for sharing. You seem dedicated to educating folks on electricity and electronics. Really commendable work and very clear explanation as always. I particularly like how you explained why semiconductors exhibit decrease in resistance with increase in temperature as compared to conductors whose resistance increase with increase in temperature.
Well done!
I can't thank you enough for finding time to go through the post. Semiconductors are the backbone of modern electronics. The development of high speed computers is the product of evolution of semiconductor.Also the high performance of communication system was hinged on improvement in semiconductor electronics.
