Group alum Dr. Konner Holden interviewed for Semi @ Oregon State: April 2023 ALD collaborations lead to workforce and next-generation packaging solutions "...Today we get an inside look at ALD from an interview with Konner Holden, a process engineer at Lam Research who earned his undergraduate and doctoral degrees from Oregon State University. Engaged in research on ALD and how it can be used for stacking/multilayer chip design, Konner first shared his academic and professional journey, his industry partnership through research at Oregon State, and finally his current work on ALD at Lam. Collaborations among academia and industry, a staple of graduate engineering programs at Oregon State, allow for mutually beneficial scenarios in which research is advanced and great hires can be made.

Getting his start in computer science and then switching to electrical engineering, Holden excelled at Oregon State as an undergraduate student, noting that he took a “deep dive into how computers work, looking at transistors, really just the heart of everything.” Staying at Oregon State for graduate school, Holden began his research into ALD under the tutelage of his advisor, John Conley, professor of electrical and computer engineering and materials science. Here Holden stated that he “began using ALD to fabricate novel electronic devices and test new materials along with new ALD processes.”

When asked why he stayed on at Oregon State for his Ph.D, Holden said, “I felt that I’d already found my home. On top of that, I had access to the Materials Synthesis and Characterization Facility at Oregon State, and there was a great clean room environment. I felt I had everything I needed and didn’t feel any reason to go anywhere else or honestly even look anywhere else.” Holden's passion for research into ALD was unabated, and he didn't miss a beat. ..."

Group's collaboration with The University of Queensland Brisbane and the Indonesian Institute of Sciences makes frontispiece of Small: Characterization of organic nanoparticle orientation in a polyurethane foam, which exhibits anisotropic mechanical properties, remains challenging. In Atomic Layer Deposition of Metal Oxide on Nanocellulose for Enabling Microscopic Characterization of Polymer Nanocomposites, John F. Conley Jr., Pratheep K. Annamalai, and co‐workers briefly demonstrate the application of atomic layer deposition to enhance the contrast of nanocellulose through a coating of alumina on nanocellulose and enabling microscopic characterisation. By incorporating alumina coated nanocellulose in a polyurethane foam, it also demonstrates nanocellulose alignment in the foam‐rise direction. Access the frontispiece here.

November 2018:
The Antenna Coupled THz (ACT) Film, our collaboration with RedWave Energy Inc., Univ. of Colorado Boulder, Univ. of Misouri, and Idaho National Labs (INL) wins an R&D 100 Award!
Converting waste heat into power represents one of the largest opportunities for bringing greater efficiency and reduced emissions to the energy sector. Using nanorectifying antenna research from INL, RedWave Energy Inc. has developed Antenna Coupled Thz (ACT) Film capable of harvesting low-temperature waste heat at power plants. Each sheet of ACT Film is made of tiny, square, gold-wire rectennas embedded in polyethylene, plastic sheeting that can be used nearly anywhere. The ACT Film absorbs heat between 70 and 250 degrees Celsius and converts it to electricity. Conceivably, composite stacks of ACT Film could be engineered to be compatible with existing power plant designs and used to replace cooling towers. By recovering 20 percent of low-temperature waste heat at a typical power plant, the electricity generated would equal the amount produced by burning 112,000 tons of coal in a year.
The R&D 100 Awards recognize the most promising new products, processes, materials, or software developed throughout the world and introduced to the market the previous year. Awards are based on each achievement's technical significance, uniqueness, and usefulness compared to competing projects and technologies.

ALD MoS2 project (sponsored by Sharp Labs of America):
From BALD Engineering, February 2016, "Oregon State present ALD of 2D alternate channel material MoS2 on 6 inch wafers" MoS2 is a two dimensional transition metal dichalcogenide material. With a direct bandgap of 1.8 eV when in monolayer morphology, it overcomes one of the limitations of graphene - the lack of a bandgap. The work demonstrates atomic layer deposition (ALD) of one to two monolayer MoS2 over 150 mm quartz and SiO2 patterned Si wafers. Applications such as an alternate channel material for MOS devices and catalysis applications are envisioned. The paper, first authored by Arturo Valdivia and entitled, "Atomic layer deposition of two dimensional MoS2 on 150 mm substrates," appeared in JVST was selected as an Editor's Pick for Feb. 2016.

From Beneath the AVS Surface, April 2016, "Atomic Layer Deposition Shown to Produce Quality 2D Thin Films," In the latest issue of the Journal of Vacuum Science and Technology A, researchers at Oregon State University and Sharp Labs of America demonstrate how they were able to successfully use a technique known as atomic layer deposition (ALD) to deposit one to two monolayers of MoS2 on large area silicon and quartz substrates..."We found that we could consistently deposit a one-to-two monolayer 2DMoS2 film uniformly over a large surface area," Conley said. "Annealing the film in sulfur allowed us to see a strong photoluminescence peak, a hallmark of a monolayer material." .pdf

From OSU COE EECS Featured Stories, 4/27/16, "Blending electrical and chemical engineering," Making advances in two-dimensional semiconducting materials was beyond the scope of what Arturo Valdivia could imagine for himself when he was growing up in the small town of Nyssa in Eastern Oregon. But his first research project as a graduate student was not only published in the Journal of Vacuum Science & Technology A, but it was selected as the “Editor’s Pick” and was on the journal’s most read list. The article was also featured in Beneath the AVS Surface, a news publication for the American Vacuum Society... - .pdf
