Advanced semiconductor devices

The first part will give an overview of semiconductor devices trends and evolutions for calculations. Limits of traditional architectures as transistors and memories will be studied. Then we will described emerging solutions for calculations and memories including devices and architectures for advanced computing and artificial intelligence. The second part will address the physics of light emitting diodes.
