Project Description
The (ultra)wide bandgap semiconductors, also known as the third and fourth generation semiconductors, have enormous potentials to revolutionize almost every industry on the planet and in space. Because of the unique and superior properties, they can be made in ultra-efficient, ultra-sensitive and ultra-reliable optical and electronic devices.
Despite being in the early phrase of development and commercialization, these semiconductors have already resulted in industries worth of hundreds of billions USD and creating numerous jobs, as well as 2014 Nobel Prize in Physics. Opening your phone, computers and anything using electricity, you will likely find plenty of them.
More potentials are to be unlocked by smart and hard-working researchers such as you. This VSRP project is offered by the Advanced Semiconductor Laboratory, a world-leading laboratory with state-of-the-art facilities in the (ultra)wide bandgap semiconductor research. The VSRP students will have the opportunity to learn the latest materials, devices, and integrated circuits. More importantly, every VSRP student will have his/her own project to solve a key problem. The project needs 4-6 months to be completed. It is going to be an exciting period with intense training and research work both theoretically and experimentally. Successful students can likely publish their results in prestigious scientific venues.
Applicants can refer to our recent papers in Nature Electronics, Advanced Materials, Nature - Light Science & Applications, Applied Physics Letters, IEEE transactions, etc.

Desired Project Deliverables
In research, no deliverables can be compared with a patent or a peer-review paper. In the past, all the VSRP students can generate patents or publish first-authored or co-authored papers in prestigious journals. The publication record has help strengthen their credentials greatly for future career development. Therefore, the incoming VSRP students are expected to do the same.
