Interface controlled thermal properties of ultra-thin chalcogenide-based phase change memory devices
Kiumars Aryana, John T. Gaskins, Joyeeta Nag +10
Phase change memory (PCM) is a rapidly growing technology that not only offers advancements in storage-class memories but also enables in-memory data storage and processing towards…
Unveiling temperature dependence mechanisms of perpendicular magnetic anisotropy at Fe/MgO interfaces
Fatima Ibrahim, Ali Hallal, Alan Kalitsov +3
The perpendicular magnetic anisotropy (PMA) at magnetic transition metal/oxide interfaces is a key element in building out-of-plane magnetized magnetic tunnel junctions for spin-tr…
The role of lighter and heavier embedded nanoparticles on the thermal conductivity of SiGe alloys
A. Kundu, N. Mingo, D. A. Broido +1
We have used an atomistic {\it ab initio} approach with no adjustable parameters to compute the lattice thermal conductivity of SiGe with a low concentration of emb…
Oxide layer boron leads to reduced symmetry spin filtering magnetic tunnel junctions
Derek A. Stewart
Experimental studies of FeCoB/MgO/FeCoB tunnel junctions indicate that boron diffuses into MgO during rf-sputtering and forms polycrystalline Mg-B-O regions. These tunnel junctions…
Properties of short channel ballistic carbon nanotube transistors with ohmic contacts
Francois Leonard, Derek A Stewart
We present self-consistent, non-equilibrium Green's function calculations of the characteristics of short channel carbon nanotube transistors, focusing on the regime of ballistic t…
Ab-initio investigation of phonon dispersion and anomalies in palladium
Derek A. Stewart
In recent years, palladium has proven to be a crucial component for devices ranging from nanotube field effect transistors to advanced hydrogen storage devices. In this work, I exa…
