Gallium nitride (GaN) is a semiconductor with dynamic chemical and electrical properties such as high voltage breakdown and saturation velocity. As a result, they are suitable for use in a wide range of switching devices. Because of its reduced power consumption and enhanced temperature tolerance and efficiency, gallium nitride is predicted to be a silicon substitute. Thus, gallium nitride semiconductor devices and their applications in inverters, electric vehicles, smart grid systems, communication devices, and other fields are gaining popularity. 

One of the key reasons fueling the market for GaN semiconductor device applications and their use in consumer electronics and the automotive industries is the broadband gap quality of GaN, which leads to its employment in novel semiconductor devices. Furthermore, its increased use in R.F. power applications has positively impacted market growth. The rise in demand and utilization of these devices in the aerospace, medical, military, and other industries is expected to drive the market even more. 

However, the COVID-19 pandemic has resulted in lockdowns in a number of major economies. As a result, electronic goods sales have decreased, and supply networks have been disrupted. Furthermore, many economies are incurring considerable revenue losses as manufacturing facilities close due to lockdowns.
