Abstract:
Recently, Racetrack Memory (RM) has attracted more and attention of memory researchers because it advantages ultra-high storage density, fast access speed, non-volatility. Prior research demonstrated that RM potential to replace SRAM for large capacity on-chip design. At the same time, also addressed design space exploration could be complicated compared traditional technologies several reasons. First, a single cell introduces device level parameters. Second, considering these device-level...
In this study, a series of ∼26 nm thick hafnium oxide films doped with different concentrations Mg were prepared by the chemical solution deposition method. With increase concentration, film undergoes phase transition from monoclinic, through orthorhombic, and then to cubic. Metal–insulator–semiconductor capacitors fabricated, ferroelectricity was verified for an concentration 0.4–3.7 mol. %. For 2.3 % Mg, remanent polarization is 16.4 μC/cm2 after wake-up process, 76.1% initial 2Pr value...
Hydration state is a key factor affecting the pore structure and mechanical properties of shale that directly impacts migration then production geofluids. We quantify impact hydration on physical through spontaneous imbibition experiments constrained by concurrent nuclear magnetic resonance (NMR) acoustic observations as diagnostics response. The long-duration (24 days) are samples from Permian Shanxi Formation Ordos Basin, complemented measurements composition properties. These shales...
Deposition of amorphous silicon thin films via plasma‐enhanced chemical vapor deposition (PECVD) and batch‐to‐batch operation under run‐to‐run control the associated chambered reactor are presented in this work using a recently developed multiscale, three‐dimensional space, computational fluid dynamics model. Macroscopic scale behaviors linked to microscopic growth dynamic boundary which is updated at each time step transient in‐batch simulations. This novel workflow distributed across 64...
Abstract HfO 2 thin film has been widely studied as the most promising candidate material for microelectronic devices. However, low leakage current density is prerequisite excellent performance of Therefore, effects substrate bias duty ratio and frequency on roughness are Y:HfO films deposited by reactive magnetron co‐sputtering method. The results illustrate that influence through grain size films. An appropriate beneficial to densification reduction current. When cycle 30.1% at 19.7 kHz,...
The increasing proportion of renewable energy sources into the power grid is calling for more regulation capacities. Electric Vehicle (EV) has a huge potential ancillary service due to its large amount in electricity market. This paper proposes multi-time scale bidding strategy EV aggregator, which considers battery degradation cost individual EVs. Firstly, with piecewise linear function, model established and incorporated optimal strategy. Secondly, calculated based on change state charge...
We study tightness properties of a Lagrangian dual (LD) bound for the nonconvex alternating current optimal power flow (ACOPF) problem. show that LD can be computed in parallel, decentralized manner. The proposed approach partitions network into set subnetworks, dualizes coupling constraints (giving function), and maximizes function with respect to variables desired bound). maximize are obtained by using proximal bundle method. is less tight than popular semidefinite programming relaxation...
We demonstrated an area emission transistor with [Ir(ppy)2pyim]PF6/PMMA as the dielectric layer. The brightness can be tuned by VDS and VGS, respectively. device performance was optimized adjusting mass concentration ratios of PMMA. Different working mechanisms devices without PMMA were investigated through Kelvin probe force microscope. doping will change surface potential [Ir(ppy)2pyim]PF6, then properties charge injection. Our research may open up a new way for development multifunctional devices.
