Meet student researchers advancing batteries, semiconductors and additive manufacturing

Why did you choose the project you’re working on?

Ever since my early academic exposure to electrical engineering, the intricacies of semiconductor manufacturing piqued my interest. The ability of these tiny components to power entire devices and systems seemed almost magical, driving my curiosity to understand the behind-the-scenes processes.

In the electrical engineering curriculum, we delve into the fundamental principles behind semiconductors, their properties and their roles in electronic devices. However, the comprehensive understanding of semiconductor manufacturing processes, from wafer fabrication to packaging, is often explored in specialized courses or through self-directed learning. My interest in the manufacturing aspect is a supplementary deep dive, building upon the foundational knowledge from my major.

How will your engineering research project impact the world?

Traditionally, semiconductor devices and printed circuit boards suffer from the gradual degradation of their metal components, primarily due to oxidation. This oxidation can lead to reduced performance, increased energy consumption and shortened device life span. By researching technologies that mitigate metal oxidation, we aim to enhance the overall efficiency and longevity of these devices, making them more sustainable and reducing electronic waste over time.

Reducing metal oxidation primarily preserves the integrity and efficiency of the metal components within semiconductor devices and printed circuit boards. Oxidation can lead to the formation of non-conductive layers on metal surfaces, which can impede electronic signals, reduce energy efficiency and even cause device failures. By curbing this oxidation, devices can maintain optimal performance levels for more extended periods, ensuring that they function as intended and don’t require frequent replacements or repairs.

Have there been any surprises in your research?

One major surprise was understanding the intricacies and nuances of the X-ray photoelectron spectroscopy, or XPS, tool. XPS has been particularly central to our testing processes. The XPS tool allows us to analyze the surface chemistry of the semiconductors by detecting the energy and number of electrons that escape from the top layers of the material when they are exposed to X-rays. This provides invaluable insight into the composition and electronic state of the materials we are examining. Additionally, we use multimeters for basic diagnostic tasks, like measuring various electrical properties such as voltage, current and resistance. A significant part of our research also involves setting up and optimizing the plasma machine for our open-air plasma experiments.

How do you see this experience helping your career?

While my aspirations may evolve with time and experience, I currently aim to work in semiconductor manufacturing or design, particularly in roles that bridge the gap between research and commercial production. In the long run, I envision myself leading research and development teams to develop next-generation semiconductor technologies, fostering innovation that can propel the electronics industry forward and make a positive impact on society. Conducting this research has been a treasure trove of experience and skill acquisition, specifically my technical proficiency, problem-solving, project management, collaboration and innovation skills.

What is the best advice you’ve gotten from your faculty mentor?

During the early stages of my research, I was working on optimizing the parameters for our open-air plasma technology. One particular experiment involved using a specific combination of power levels and exposure times to enhance the quality of the semiconductor surface. However, when the actual experiment was conducted, not only did it not yield the expected improvements, but it also degraded the semiconductor metal surface. At first, I was disheartened, feeling like I had wasted precious time and resources. However, recalling my faculty mentor’s advice that “no experiment is a failure,” I began to analyze the results more critically. While the initial objective was not met, the unexpected outcome provided valuable insights into the limitations of the technology under certain conditions. This “failure” proved instrumental in redefining our approach and parameters for subsequent experiments, ensuring that we avoided similar pitfalls.

Why should other students get involved in FURI?

Engaging with FURI offers students unparalleled access to a vibrant community of researchers and industry experts, facilitating meaningful networking opportunities. But more than that, FURI provides a hands-on experience that deepens one’s comprehension of their chosen field.

What made you want to get involved in FURI? 

During my first semester at ASU, I was in Professor Mallik’s Electrical Engineering Fundamentals class. It was in that class that I learned about FURI from him and a classmate, both of whom encouraged me to participate in the program. I was uncertain about it because I had just started my ASU career, and my technical knowledge I felt was behind my peers’. I jotted down a note in the margin of my notebook in one of [Professor Mallik’s] lectures about amplifying voltage and kinetically charged batteries. I told myself that come spring if he had not signed on as a mentor to anyone else’s FURI project, I would ask him to be my mentor. Fast forward to the spring semester and he indeed had not agreed to mentor any undergraduate students for the upcoming fall. I proposed my idea, and he told me he had not worked in that space before but would be willing to mentor me in the fall semester.

How will your engineering research project impact the world?

Through mass social media consumption, I learned that prosthetics can die at inopportune moments throughout the day, leaving the user stuck. By utilizing kinetically charged batteries the user could prolong the device’s life to last the whole day. Kinetically charged battery amplification and optimization is not just limited to prosthetic devices — it has the potential to be used in communication devices, GPS devices, insulin pumps, heart monitors and even your smartphone. This will not replace charging the device entirely but should be able to prolong the use of that single tethered charge.

How do you see this experience helping with your career or advanced degree goals?

My career goal is to design and create robotic medical assistive devices that combine a splash of fashion with robotics. As part of this objective, I am focused on optimizing the power supply of devices because of the positive impact that would have on user experience and quality of life. Additionally, I seek out supplemental projects in fields I have little to no knowledge of but that can enhance my degree path by aligning with my career goals. It offers a venue and the motivation to learn the material and really expand my knowledge, making me a better engineer.

What is the best advice you’ve gotten from your faculty mentor?

The best advice given to me by my mentor is not anything he said — it is what he has done. Although the field of kinetically charged batteries falls outside of his active research areas, he did not turn me away when I proposed it as my FURI topic. He listened to my ideas and then guided me through the project’s different steps and processes. I have learned a great deal from this approach and plan to use it in other areas of my life.

Why should other students get involved in FURI?

FURI gives you the opportunity to get hands-on lab and research experience while pursuing a topic of interest that may not fall within the scope of your classes. Not many undergraduate students get the opportunity to pursue their own research. Thus, it is a valuable experience for any college student.
