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…
Efficient spin injection into graphene through a tunnel barrier: overcoming the spin conductance mismatch
Qingyun Wu, Lei Shen, Zhaoqiang Bai +4
Employing first-principles calculations, we investigate efficiency of spin injection from a ferromagnetic (FM) electrode (Ni) into graphene and possible enhancement by using a barr…
Electron transport across a metal/MoS interface: dependence on contact area and binding distance
Zhaoqiang Bai, Troels Markussen, Kristian S. Thygesen
We investigate the nature of electron transport through monolayer molybdenum dichalcogenides (MoX, X=S, Se) suspended between Au and Ti metallic contacts. The monolayer is plac…
