Recently, much attention have been drawn to converse magnetoelectric(CME) effect, as well as electric field modulated transport properties in magnetoelectric heterostructure composites[1-3]. In situ Electric field (E) modulating magnetic and electric transport properties have be well achieved in magnetoelectric bilayer films[2-4]. These excellent investigations open a new pathway to the electronic...
Gold nanoparticle arrays are fabricated for surface-enhanced Raman scattering (SERS) and the effect of experimental parameters such as annealing temperature and array thickness of nanoparticles on the SERS signals are investigated. The particle distribution and particle size are dense and uniform on the glass substrate when the 10nm gold film was annealed at 270 ºC and strong SERS signals for Rhodamine...
Poly crystalline CuxO films produced by plasma oxidation are investigated for nonvolatile memory applications. Reversible bistable resistive switching from a high-resistance state to a low-resistance state, and vice versa, is observed in an integrated Al/CuxO/Cu structure under voltage sweeping. More than 3000 repetitive cycles are observed in 180-mum memory devices with an on/off ratio of ten times...
Polyimide (PI) has been widely used in integrated circuits and semiconductor devices as multilevel insulators and surface-passive materials (1.2). As the sodium ions and other alkali metal ions are the major factors of instability of semiconductor devices, the investigation of migratory characteristics of sodium ions in PI has aroused great interest among insulation researchers. Unfortunately, at...
