GaN materials have found a large hole to fix in the world today. Keeping an eye over its variable bandgap and high-density electrons. Optoelectronic devices are now on their peak with its high stability and high electron carrying property. Starting with LED GaN has shown significant development in its application with outside world. Red LEDs were difficult and expensive before the entrance of GaN LEDs by giving us the option to choose substrate that makes GaN materials more flexible and reliable. Scientists today are working on the ways to avoid natural defects like quantum confined stark effect and black barrier effect associated with buffer layer. Amplifiers that use GaN technology are now available and give us better performance than the conventional ones. Other applications such as radars and nanomaterials are extensively investigated for correction of defects and improvement of quality. Wireless communications are being improved with GaN and its substrates. With the help of GaN today we can pinpoint locations with near-perfect accuracy and save power loss in conversions. Although we may have improved our quality, mass production is still a long way because of expensive materials. Work is going on to bring down the price and make it ready for commercial purposes and help humans as soon as possible in the near future.
