Scanning probe lithography (SPL) is a promising candidate approach for desktop nanofabrication, but trade-offs in throughput, cost, and resolution have limited its application. The recent development of cantilever-free scanning probe arrays has allowed researchers to define nanoscale patterns in a low-cost and high-resolution format, but with the limitation that these are duplication tools wher...

we design a novel nano-ring resonator using two-dimensional photonic crystal (2d-phc), for bio-sensing applications. the structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. these are configured by removing one row of air holes. the refractive index of sensing hole is changed by binding an analyte. hence, intensity of the transmission spectrum...

Amajor limitation for future nanotechnology, particularly for bottom-up manufacturing is the non-availability of 2-dimensional massively parallel probe arrays. Scanning proximity probes are uniquely powerful tools for analysis, manipulation and bottom-up synthesis: they are capable of addressing and engineering surfaces at the atomic level and are the key to unlocking the full potential of Nano...

A new and simple method for nanostructuring using conventional photolithography and layer expansion or pattern-size reduction technique is presented, which can further be applied for the fabrication of different nanostructures and nano-devices. The method is based on the conversion of a photolithographically patterned metal layer to a metal-oxide mask with improved pattern-size resolution using...

Quantum nano-structures are likely to become primary components of future electronic devices. Presently the majority of these structures, such as nano-mechanical resonators, semiconductor quantum dots, single electron transistors, and similar low dimensional structures, exist as prototypes in research laboratories or just being contemplated. Practical realization of quantum devices faces a numb...

This paper developed an active scanning probe array. The probe array consists of 16×2 probes thermally actuating and sensing. The 32 probes are integrated with Ti/Pt temperature sensors and bimorph thermal actuators. Each probe is a Si3N4 cantilever equipped with a sharp nano scale pyramid tip at its free end. When one of the probes is actuated, its neighboring probes can provide temperature se...

In this work the effect of substrate roughness on the adhesion of gecko foot-hair like nano structures as opposed to solid elastic materials is described and models of both synthetic nano-hairs and hair-substrate interaction are developed. First, by combining linear beam theory and geometric constraints, a nonlinear elastic model for the hair is derived. Then it is shown how for a given random ...
