Semiconductors in the Information Age

About this Course

About the Course

In this course Professor Oleg Makarovskiy (University of Nottingham) explores semiconductors and their relevance in the current Information Age. In the first mini-lecture, we introduce the ages of human advancement, from the Stone Age up until the current Information Age, and consider the advancements in computers and information made in the 20th century. In the second mini-lecture, we discuss what a semiconductor is and how you can make one using electrons and ‘holes.’ In the third mini-lecture, we consider how semiconductors can be used to create light of various colours (LEDs) and transform light into electrical energy (solar cells). In the fourth mini-lecture, we explore how we can control semiconductor colour and how we can make low-dimensional semiconductors, such as quantum dots. In the fifth mini-lecture, we focus on understanding diodes and transistors and how these can be used to create microchips used in computers. Finally, in the sixth mini-lecture, we consider the next advancement in our Information Age, quantum information technology, and the role semiconductors play in this new Quantum Information Age.
