Research Reveals Insight into Stability of Thin Films Just as every snowflake is different from any other, an individual snowball exhibits exceptionally different properties than the thousands of snowflakes that make it up. A group led by Dr. Tai-Chang Chiang of the University of Illinois studies how thin films of materials—such as lead films deposited on silicon—exhibit different traits than their more massive cousins. Most recently, they have found that it is possible to turn unstable films into stable ones.
