Experimental and theoretical results are presented for segregation of dopants in single-crystal semiconductors grown by molecular beam epitaxy (MBE). Experimental results include Sn doping of GaAs, Si doping of Ga(,x)Al(,x)As ...

The nonequilibrium glassy state of polymers has been examined using Fourier-Transform Infrared (FTIR) spectroscopy. The nonequilibrium nature of polymer glasses induces a physical aging process which results in time dependent ...

Interfacial microstructures in two divorced graphitic eutectics have been investigated using transmission electron microscopy (TEM). Both systems show a coarse minor precipitate, graphite, whose morphology depends strongly ...

An investigation has been made of the internal hydrogen embrittlement of high strength aluminum alloys. The majority of experiments were performed using a high purity Al-5.5 wt pct Zn-2.5 wt pct Mg alloy hydrogenated to ...
