Enhancement and reduction of one-dimensional heat conduction with correlated mass disorder
Zhun-Yong Ong, Gang Zhang
Short-range order in strongly disordered structures plays an important role in their heat conduction property. Using numerical and analytical methods, we show that short-range spat…
Anisotropic charged impurity-limited carrier mobility in monolayer phosphorene
Zhun-Yong Ong, Gang Zhang, Yong Wei Zhang
The room temperature carrier mobility in atomically thin 2D materials is usually far below the intrinsic limit imposed by phonon scattering as a result of scattering by remote char…
Microstructural Evolution of Charged Defects in the Fatigue Process of Polycrystalline BiFeO3 Thin Films
Qingqing Ke, Amit Kumar, Xiaojie Lou +4
Fatigue failure in ferroelectrics has been intensively investigated in the past few decades. Most of the mechanisms discussed for ferroelectric fatigue have been built on the "hypo…
Low-bias Negative Differential Resistance effect in armchair graphene nanoribbon junctions
Suchun Li, Chee Kwan Gan, Young-Woo Son +2
Graphene nanoribbons with armchair edges (AGNRs) have bandgaps that can be flexibly tuned via the ribbon width. A junction made of a narrower AGNR sandwiched between two wider AGNR…
Large magnetoresistance from long-range interface coupling in armchair graphene nanoribbon junctions
Suchun Li, Young-Woo Son, Su Ying Quek
In recent years, bottom-up synthesis procedures have achieved significant advancements in atomically-controlled growth of several-nanometer-long graphene nanoribbons with armchair-…
Competing for Attention in Social Media under Information Overload Conditions
Ling Feng, Yanqing Hu, Baowen Li +3
Although the many forms of modern social media have become major channels for the dissemination of information, they are becoming overloaded because of the rapidly-expanding number…
