will William Mohr, NUFAB, Engineer Research Associate


What technical expertise do you offer?

I have been working in semiconductor manufacturing for a number of years and recently returned to academia. My previous experience involved research and developmental work around improving LEDs using MOCVD as well as working as an equipment engineer for a MOCVD foundry that produces VCSELs, EELs, and power and RF devices. My expertise centers around research and development of III-V materials as well as extensive work on maintaining, repairing, and troubleshooting vacuum systems. Since transitioning to NUFAB, I have expanded my work to other deposition techniques such as other chemical vapor deposition and physical deposition techniques.


How do you facilitate research collaboration?

At NUFAB one of our goals is to help users with their research. We advise, train, and troubleshoot processes with the users to help them get the best result for their research -- this naturally leads to collaboration. I have developed a number of processes for users on the ALD recently, including ZnO, Pt, Ti, and SiO2 films to meet users research needs. I am also open to working with other collaborators at Northwestern on research projects that involve equipment that we have a NUFAB be it fundamental materials research or process development.


What inspired you to work in this field?

I have always enjoyed learning about how things work. Science is a field that lets you explore that natural curiosity. In particular, I was drawn to micro fabrication and semiconductors due to the field being still very new and constantly evolving. This enables you to contribute in some small way to the evolution of the field as a whole as well as gain understanding of the challenges and solutions that arise along the way. 


What are the everyday practical applications of your research/work? How does what you’re doing make a difference to non-scientists?

From the VCSELs that enable the facial recognition software on your phone, 5G technology, sensors in self driving cars, and medical devices that measure concentrations of various chemicals in your body -- semiconductors and MEMS have become an integral part of modern society. 


What’s the most interesting project or achievement that you’ve been involved in at NUANCE?

I’ve worked on a number of interesting projects – it is hard to pick just one. The ones that are most interesting to me are the ones that are challenging and push me to learn something new.


What excites you most about the future of nanotechnology?

I am excited to see how our interaction with medical technology evolves over time. I expect to see more interaction between technology and medical devices/implants. We have not yet seen any large changes in this area but I think this is an area with a lot of potential. This kind of technology has far reaching applications for improved health care to the way we learn and access information.
