Revolution for Solar Power & Light Emitters

Louise Bailey, a Ph.D. student at the University of Warwick describes her research into nitride semiconductors with real-world implications. This video introduces examples of semiconductor devices, e.g. mobile phones, solar cells, and light-emitting-diodes, to show the wide field of application and what potential benefits research into nitride semiconductors has for consumers. An explanation of semiconductor energy bands with animations are followed by Louise Bailey demonstrating absorption spectroscopy, including a display of a bright orange indium gallium nitride sample. To conclude the possibilities of using indium-gallium nitride for illumination on Earth and in space, its many advantages, e.g. compact, reliable, relatively inexpensive, and highly efficient, and how nitride semiconductors have the potential to change energy consumption, defence and the environment are discussed.

A very informative video with good presentation. Well define structure for the information given. A very bright young girl.
