For his research, Gilbert won the physics, astronomy and engineering category for his research work and a superior rating on his poster. More than 80 graduate and undergraduate students presented their research at the conference. In addition, he accepted an offer to join the prestigious international science and engineering society.
The novel semiconductor is an alloy of cobalt, iron, chromium and aluminum in which part of the aluminum was replaced with silicon. Simeon Gilbert, a South Dakota State University physics major won 1st place at the annual Sigma Xi national conference for his work. He tested the magnetic and structural properties of a novel magnetic semiconductor material.
“Materials for computers need to work at, and somewhat above, room temperature,” Gilbert said. With the aluminum, this material maintained its magnetic properties with temperatures up to 450F, but replacing a fraction of the aluminum with silicon allows the researchers to push that working temperature closer to 1,000F. Both materials were developed in collaboration with Nebraska researchers.
“This is a huge improvement,” Gilbert said. His research advisers are professor Yung Huh and assistant professor Parashu Kharel. The research was done through SDSU Academic and Scholarly Excellence and Research and Scholarship Support Funds.
“When it comes to supercomputers, the power savings are huge,” he added. Researchers at SDSU and UNL will continue working on this promising material. http://www.newswise.com/articles/testing-new-magnetic-semiconductor-material
