Ionization Induces Healing of Defects in Silicon Carbide
August 20, 2015 — Understanding of ionization-induced healing has been advanced by the discovery of substantial annealing of pre-existing defects and restoration of structural order in silicon carbide (SiC) from energy transferred to electrons by energetic ions via inelastic ionization processes.
Patterning Semiconductor Building Blocks in 2D Crystals
July 22, 2015 — For the first time, researchers have synthesized lateral semiconductor heterojunctions in lithographically patterned arrays within a two-dimensional semiconductor crystal monolayer by a novel process that selectively converted exposed regions of a monolayer of MoSe2 to MoS2 using laser-deposited sulfur.
Guidelines Clarify Origins of Ferroelectric Signals
July 21, 2015 — Recent developments in piezoresponse force microscopy (PFM) and spectroscopy revealed the presence of electromechanical hysteresis loops in a variety of materials including inorganic oxides, polymers and bio systems. This behavior is often (mis)interpreted as evidence of ferroelectricity.
Easy phase transitions spur high piezoelectric responses
July 14, 2015 — Theoretical calculations, based on newly obtained experimental geometries in strained BiFeO3 thin films, predict an almost barrierless transition between co-existing phases. This facile transition provides insight into the origin of the high electromechanical responses found in coexisting phases in this Pb-free material.
HPC Industry Leaders Develop State-of-the-Art Network Communication Framework for Next Generation Programming Models
July 13, 2015 — UCX (Unified Communication – X) will provide platform abstractions supporting various communication technologies for high-performance compute and data platforms
