601 Myers, Chris J.Effcient verification of hazard-freedom in gate-level timed asynchronous circuitsThis paper presents an efficient method for verifying hazard freedom in timed asynchronous circuits. Timed circuits are a class of asynchronous circuits that utilize explicit timing information fur optimization throughout the entire design process. In asynchronous circuits, correct operation require...2003
602 Scarpulla, MichaelEffect of film thickness on the incorporation of Mn interstitials in Ga1-xMnxAsWe have investigated the effect of film thickness on the distribution of Mn atoms at various lattice sites in Ga1−xMnxAs thin films. We find that the growth surface acts as a sink facilitating the outdiffusion of Mn interstitials sMnId, and thus reducing its concentration in the film. The outdiffu...Interstitials; Gallium arsenide2005
603 Stringfellow, Gerald B.Effect of growth rate on step structure and ordering in GaInPCuPt ordering is widely observed in GaInP epitaxial layers grown by organometallic vapor phase epitaxy. The formation of this spontaneously ordered structure during epitaxial growth is intimately related to the atomic-scale physical processes occurring on the surface, specifically surface reconst...Atomic force microscopy; Organometallic vapor phase; Crystallographic plane1997
604 Balasubramonian, RajeevThe effect of interconnect design on the performance of large L2 cachesThe ever increasing sizes of on-chip caches and the growing domination of wire delay have changed the traditional design approach of the memory hierarchy. Many recent proposals advocate splitting the cache into a large number of banks and employ an on-chip network to allow fast access to nearby ban...2006

611 Stringfellow, Gerald B.; Rieth, Loren W.Effects of Br and Cl on organometallic vapor phase epitaxial growth and ordering in GaInPCuPt ordering in GaInP has significant effects on the electrical and optical properties. In fact, band gap reductions as large as 160 meV are potentially useful for devices. Thus, control of ordering is important.
