摘要:
III-nitride wide bandgap semiconductors as the most important part of the third-generation semiconductor have superior optoelectronic properties. In the past decades, III-nitride optoelectronics have led to revolutionary innovations in numerous industries. The invention of blue LED, in particular, has been awarded by the 2014 Nobel Prize in Physics. Despite these progress, there are still enormous potentials for research and applications in the UV spectrum. For instance, UV LED can fundamentally change the entire sterilization industry. In addition, UV laser can revolutionize the communication and biochemical detection fields. This seminar will focus on the deep UV lasers and emerging B-III-N materials for UV devices. In addition, the seminar will discuss the research on the polarization toolbox that can lead to numerous device innovation and improvements.
