Interacting electron ripples provide clues to superconductivity

 

Interacting electron ripples provide clues to superconductivity A theoretical prediction is confirmed by atomic-scale microscopy

Rapid computational prediction of crystalline polymorphism

 The ability of an organic molecular solid to crystallize into different structures is  a phenomenon known as polymorphism.  Polymorphism is an issue of major concern in the pharmaceutical industry.  In many drug compounds, some fraction

MoO3 Films for Efficient Hole-Injection in Organic Electronics

Transition-metal oxides (TMO), such as molybdenum tri-oxide (MoO3), are promising hole-injection electrode materials for organic electronics because of their large work function and high conductivity. They are superior to the widely used organic polymer PEDOT:PSS which causes device degradation. However, deposition of MoO3 layers

Topological Surface States Penetrate Through Surface Barriers

Topological surface states are a new class of novel electronic states that are potentially useful for quantum computing or spintronicapplications. Unlike conventional two-dimensional electron states, these surface states are expected to be immune to localization and to overcome barriers caused by material imperfection.

See how they run... electrons on the surface of a novel insulator

Novel electronic applications often result from fresh theoretical insights into long-familiar materials. Recently, strong interest has focused on the “topological insulators”, notably Bi2Se3and Bi2Te3. In these solids, the electrons on the surface display highly unusual properties.
