This paper describes a nano-scale tensile test to study the fatigue properties of LPCVD silicon nitride thin films using a novel electrostatic actuator design. Mechanical-amplifier devices made in silicon nitride thin films can apply controllable tensile stress (2.0–7.8 GPa) to test structures with relatively low actuation voltages (5.7–35.4 VRMS) at the resonant frequencies of the devices. The...

We report the transport behavior of an open-end metallic single wall carbon nanotube (SWCNT) with and without local structural defects using the non-equilibrium Green’s functions approach together with the density functional theory (DFT). The transmission spectra and the projected density of states for the devices such as SWCNT (3, 3), (4, 4), (5, 5) and (6, 6) with and without defects were com...

Nanoscaled materials are attractive building blocks for hierarchical assembly of functional nanodevices, which exhibit diverse performances and simultaneous functions. We innovatively fabricated semiconductor nano-probes of tapered ZnS nanowires through melting and solidifying by electro-thermal process; and then, as-prepared nano-probes can manipulate nanomaterials including semiconductor/meta...

UNLABELLED Nano-floating gate memory devices (NFGM) using metal nanoparticles (NPs) covered with an insulating polymer have been considered as a promising electronic device for the next-generation nonvolatile organic memory applications NPs. However, the transparency of the device with metal NPs is restricted to 60~70% due to the light absorption in the visible region caused by the surface plas...

Nanoelectronic devices form the building blocks of the nanoscaled systems and require innovative technologies for their realization. Single Electron Transistors (SET) is a novel class of nano transistor which operates on the principle of Coulomb blockade. Coulomb blockade effects become dominant when the device dimensions approach few nano-meters. The SET devices are potential candidates for ap...

Copper nanoparticles are being applied in the biosensors, engineering, electronic devices, and technology fields. A key advantage of nanomaterials is that their properties differ from bulk with same composition. However, application nano-copper particles for jewelry artwork has not yet been revealed. We discovered compared nano-sized copper fabrication micro-copper particles. The nano- micro-si...

Quantum nano-structures are likely to become primary elements of future devices. However, there are a number of significant scientific challenges to real world applications of quantum devices. These include de-coherence that erodes operation of a quantum device and control issues. In nature, certain processes have been shown to use quantum mechanical processes for overcoming these barriers. One...
