Mechanism for bistability in organic memory elements
We demonstrate that the resistive switching phenomenon observed in organic semiconductor layers containing granular metal particles conforms to a charge storage mechanism described by Simmons and Verderber @Proc. R. Soc. A 391, 77 ~1967!#. The space-charge field due to the stored charge inhibits further charge injection from the electrodes. The equilibrium current–voltage curve is N shaped and ...
متن کاملAnalysis of Dislocation Mechanism for Melting of Elements: Pressure Dependence
In the framework of melting as a dislocation-mediated phase transition we derive an equation for the pressure dependence of the melting temperatures of the elements valid up to pressures of order their ambient bulk moduli. Melting curves are calculated for Al, Mg, Ni, Pb, the iron group (Fe, Ru, Os), the chromium group (Cr, Mo, W), the copper group (Cu, Ag, Au), noble gases (Ne, Ar, Kr, Xe, Rn)...
متن کاملAnalysis of Dislocation Mechanism for Melting of Elements
The melting of elemental solids is modelled as a dislocation-mediated transition on a lattice. Statistical mechanics of linear defects is used to obtain a new relation between melting temperature, crystal structure, atomic volume, and shear modulus that is accurate to 17% for at least half of the Periodic Table.
متن کاملMechanism Design for Set Cover Games When Elements Are Agents
In this paper we study the set cover games when the elements are selfish agents. In this case, each element has a privately known valuation of receiving the service from the sets, i.e., being covered by some set. Each set is assumed to have a fixed cost. We develop several approximately efficient strategyproof mechanisms, each of which decides, after soliciting the declared bids by all elements...
متن کاملClassifying Architectural Elements as a Foundation for Mechanism Matching
Building a system at the architectural level can be thought of as decomposition into components followed by a series of exercises in matching. Components must be composed with each other via matching mechanisms; matching signatures within those mechanisms ensure that data and control will flow through the system; and matching semantics among the components ensures that the system will meet its ...
