(1) While this boosted the Industrial Revolution leading to a global economic growth, the release of greenhouse gases contributed to the environmental concerns we are experiencing nowadays. (2) A new collective conscience is globally spreading to replace the old carbon-based society with a carbon-neutral one.

AlN interlayer-induced reduction of dislocation density in the AlGaN epilayer† The emerging ultrawide-bandgap AlGaN alloy system holds promise for the development of advanced materials in the next generation of power semiconductor and UV optoelectronic devices. Within this context, heterostructures based on III-nitrides are very popular in view of their applications as electronic and optoelectronic components.
