Increased interest in renewable generation has made siting constraints more
prominent in power system planning. In addition the power system is increasingly being
considered as one of many coupled critical infrastructure systems in nexus’ such as the foodenergy-water nexus and the gas-electricity nexus. This paper describes a power system
planning approac... Continue Reading

Monolayer WSe2 is a two-dimensional (2D) semiconductor with a direct band gap, and it has been recently explored as a promising material for electronics and optoelectronics. Low field-effect mobility is the main constraint preventing WSe2 from becoming one of the competing channel materials for field-effect transistors (FETs).

A source line sensing (SLS) scheme is presented, along with a corresponding memory core circuit architecture, for the sensing operation of magnetoelectric random access memory (MeRAM). Compared to a conventional bit line sensing (BLS) scheme, the proposed SLS, which exploits the voltage controlled magnetic anisotropy (VCMA) effect, applies a voltage across the magnetoel...

Current-induced spin-orbit torques (SOTs) in structurally asymmetric multilayers have been used to efficiently manipulate magnetization. In a structure with vertical symmetry breaking, a damping-like SOT can deterministically switch a perpendicular magnet, provided an in-plane magnetic field is applied.

Compared with current-controlled magnetization switching in a perpendicular magnetic tunnel junction(MTJ), electric field- or voltage-induced magnetization switching reduces the writing energy of the memory cell, which also results in increased memory density. In this work, an ultra-thin PZT film with highdielectric constant was integrated into the tunneling oxide layer... Continue Reading

Distributed generation takes center stage in today’s rapidly changing energy landscape. Particularly, locally matching demand and generation in the form of microgrids is becoming a promising alternative to the central distribution paradigm. Infrastructure networks have long been a major focus of complex networks research with their spatial considerations.

We report electric-field-induced switching with write energies down to 6 fJ/bit for switching times of 0.5 ns, in nanoscale perpendicular magnetic tunnel junctions(MTJs) with high resistance-area product and diameters down to 50 nm. The ultra-low switching energy is made possible by a thick MgO barrier that ensures negligible spin-transfer torque contributions, along wi... Continue Reading

Semiconducting single-wall carbon nanotubes (SWCNTs) with long lengths are highly desirable for many applications such as thin-film transistors and circuits. Previously reported length sorting techniques usually require sophisticated instrumentation and are hard to scale up. In this paper, we report for the first time a general phenomenon of a length-dependent precipita... Continue Reading

In many of the regions with abundant solar energy, atmospheric aerosols, and dust in particular, comprise a pressing issue in harnessing their energy potential. A better understanding of the natural and environmental boundaries of energy systems can yield to performance optimization of current technology. This work aims to incorporate the analysis of atmospheric dust in... Continue Reading

In this paper we introduce a decision support system framework termed the Integrated Energy Decision Support System (IEDSS). IEDSS was developed for energy planning at national and regional levels to inform energy planners at multiple levels of government. IEDSS employs system dynamics modeling to enable the rapid evaluation of the outcomes of different supply and deman... Continue Reading
