Whisker Nucleation by Slip-Assisted Grain Rotation During Thermal Cycling
As a result of thermal cycling, polycrystalline tin films with a large in-plane grain size relative to film thickness on copper substrates show grain boundary (GB) sliding, creep, yielding, and nucleation of s...

Investigation of Thermal Properties and Thermal Reliability of Ga-based Low Melting Temperature Alloys as Thermal Interface Materials (TIMs)
have been proposed as candidates for (TIMs) due to their high thermal conductivity (~30 W/m*K) and liquidity. However, poor wettability as well as embrittling and corroding effect of Ga on metals have limit...
