Shaping Matter with Acoustic Waves: From Particles to Functional Structures

open access: yesAdvanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Defects in silicon nanowires [PDF]

open access: yesApplied Physics Letters, 2006
Defects in silicon nanowires have been investigated using the electron spin resonance (ESR) method. The ESR signals consist of three features: a strong resonance at g=2.00249, a weak line at g=2.00048, and a broad feature at g=2.00541. From the saturation behavior and oxidation-related and temperature dependence analysis, we ascribe that the strong ...
