Cushman to Receive the Graduate Excellence in Materials Science (GEMS) Award in MS&T 2016

Posted: Aug 24, 2016

PhD Chemistry student Cody V. Cushman has been selected as a finalist for the Graduate Excellence in Materials Science (GEMS) award by The American Ceramic Society (ACerS).

The GEMS awards “recognize the outstanding achievements of graduate students in Materials Science and Engineering” and are open to all graduate students who make an oral presentation in any symposium or session at the annual Material Science & Technology (MS&T) Conference. 

Each finalist will be awarded a cash honorarium of $100 and a certificate from The American Ceramic Society during the conference in Salt Lake which will be held on October 26th of this year. Depending on the quality of Cushman's presentation, he will receive either the Sapphire or Diamond GEMS award for student research excellence.

Cushman will delve into flat panel displays during his oral presentation entitled : "Multi-instrument depth profiling of advanced glass materials." Flat panel displays are an integral part of smart phones, televisions, laptops, tablets, and other consumer electronic devices. Displays are microfabricated devices, and most displays are fabricated on specialty glass substrates engineered to meet the demands of the display industry. The surface morphology, composition, and reactivity of display glass can have a profound influence on device yield, performance, and life of flat panel displays. Cushman's research uses a suite of surface sensitive techniques including X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (ToF-SIMS), low energy ion scattering (LEIS), and spectroscopic ellipsometry (SE) to understand how the surface composition of display glass changes in response to chemical treatments used during the display manufacturing process. These techniques work together to provide a detailed picture of the chemistry of display glasses as a function of depth. This research is an important step towards developing the next generation of flat panel display substrates.
