The H-graphite interaction is studied for the first time in the framework of density functional theory. A coronene-like Ž . model of the 0001 graphite surface is considered. LSD and LSDqGGA results are presented for both a planar substrate and for considering substrate relaxation. Two adsorption regions separated by a barrier are found: a physisorption region ̊ ̊ around 3 A from the surface and a...

Monolayer Tungsten Diselenide (WSe2) exhibits tremendous advantages as a channel material for next-generation field-effecttransistors (FETs). This paper reviews the relevant physics and properties of WSe2 and highlights the excellent scalability of monolayer WSe2 for ultra-short channel (sub-5 nm) FETs. The crucial role of metal-WSe2 contacts in determining the performance of monolayer WSe2 FET...

Non-functional requirements are commonly called the qualitative aspects of a system -testability, mobility, and scalability, to name a few. However, when taking a holistic view of a system, non-functional requirements take on a quantitative nature. This paper will describe the Requirements Hierarchy Approach (RHA), a quantifiable method to measure and manipulate the effect non-functional requir...

Mobile data traffic has increased significantly due to the evolution of wireless communication technologies. The Information Centric Network paradigm is considered as an alternative bypass restrictions imposed by traditional IP networks, especially those related with mobility its users. Despite potential advantages this regarding mobile environments, several research challenges remain unaddress...
