Abstract:
As an Eagle Scout, it is no surprise that Gregory Ten Eyck would be an innovator with a deep respect for the environment. But he has taken these values to a whole new level, developing inventions that could lead to better fuel cells, reduce the impacts of carbon dioxide, and create the next generation of super-efficient microelectronics.

Commencement 2007: Engineering a Sustainable Future

Troy, NY | Posted on May 1st, 2007

Ten Eyck will receive a Ph.D. in electrical engineering at Rensselaer Polytechnic Institute's 201st Commencement on May 19.

The son of an Air Force officer, Ten Eyck spent his early childhood moving around the country. His family eventually settled in Maryland, where he went through junior and senior high school.

It seems that Ten Eyck was born to be an electrical engineer. His family, including an older brother and two older step-sisters, always looked to him to fix everything from the VCR to the microwave. He recalls being the family's go-to guy on anything electronic, and he still gets late-night calls for computer tech support.

He earned his bachelor's in electrical engineering from Virginia Tech, and then co-founded a company that built photonic and micromachined components. The company would grow to include more than 225 employees. After this experience, Ten Eyck decided to pursue his Ph.D. and was accepted to Rensselaer in 2003.

While at Rensselaer, Ten Eyck became a Graduate Assistant in Areas of National Need (GAANN) fellow. This prestigious fellowship through the U.S. Department of Education has paid for his entire graduate education and given him the freedom to pursue his own research. He also was a fellow in Rensselaer's Integrative Graduate Education and Research Traineeship (IGERT) program in terahertz research, which is funded by the National Science Foundation. Both programs are managed by Gwo-Ching Wang, professor and chair of physics, applied physics, and astronomy. Ten Eyck worked closely with Wang during his time at Rensselaer, along with his primary research advisor Toh-Ming Lu, the R.P. Baker Distinguished Professor of Physics.

Ten Eyck's research focuses on the deposition of extremely thin metal films. He has invented three methods that could have broad implications for the next generation of microelectronics, as well as applications in energy and the environment. His innovations made him a finalist for Rensselaer's first-ever Lemelson-Rensselaer Student Prize and have earned him the respect of researchers in his field and in industry.

First, Ten Eyck developed a method to deposit metals on polymers. This application of atomic layer deposition (ALD) has been envisioned by scientists for years as a way to improve circuit function and reduce circuit size, but it has never been accomplished. Ten Eyck's ALD process could enable industry to create devices that were thought to be years in the future.

Using his expertise in metal ALD, Ten Eyck also learned to create large metal surfaces with thin, uniform layers of metal over a porous insulating material to create a highly efficient energy storing surface. He then took this invention a big step further, creating a surface that could combine carbon dioxide with hydrogen to form methane gas at room temperature.

Such a conversion normally requires temperatures upward of 300 degrees Celsius. This key breakthrough has the potential to transform greenhouse gases into useful natural gas. The process could allow for the production of new energy storage devices and conversion technologies such as fuel cells.

Finally, Ten Eyck has envisioned a novel way of connecting circuits that greatly reduces the size of the circuit and can improve device performance. In order to keep making smaller electronics, manufacturers need smaller integrated circuits. One method to reduce circuit size is to stack circuits vertically and solder the interface to connect them electrically. The problem to date with this process is that the welding requires high temperatures or a mixing of metals that can damage circuit performance.

Ten Eyck and fellow graduate students have created a nano-welding process that welds at a reduced temperature. This advance will allow manufactures to use highly efficient, pure metals (like copper) rather than metals that have a lower melting point (like lead) and negative environmental impacts.

Ten Eyck plans to pursue a career with a government or private industry laboratory, helping to create the next wave of sustainable technologies and innovative electronics.
