A maskless nano-lithography method by using polystyrene spheres (PSs) self-assembled on silver slab (NSSL) was proposed in [optics express
Vol. 16
No. 19 (2008) 14397]. Following that
to break the limitations in resolution and PSs period of NSSL method
in this paper
we present PSs immersed super-resolution lithography (NSISL) technology by embedding the PSs into appropriate material to improve the efficiency of the surface plasmon excitation. The energy modulating mechanism and the rules of the resolution affected by silver slab were studied by calculating and analysing the energy distribution. The curve of the lithography resolution versus the silver thickness was presented. In order to verify this method
contrast analysis was carried out with NSSL. The results show that the lithography resolution is improved efficiently. Taking a specific configuration with PS diameter of 600nm as an example
the resolution was improved to 54nm from 190nm with Ag thickness of 25nm. Based on the calculation results
we carried out the experiments. Nano holes with dimension of 75nm and period of 600nm were obtained. 2012 IEEE.

In order to realize real-time measurement based on image
proposes a design project of embedded image grabber and processing system based on camera link interface. The system adopts FPGA+DSP structure design. DSP used to process the image and send out processing results to external. FPGA adopts modularize design. It contains camera link interface module
image memory module
DSP connection module and so on. The experiment results show that the system design flexibility
small cubage
high real-time image processing
and can fulfil the requirement of real-time measurement. 2012 TSI Press.

Mn1 - xCrxTe films with x = 0
0.02
and 0.05 was synthesized by pulsed laser deposition and crystallize in hexagonal NiAs-type structure. The spin glass behavior predicted before by Monte Carlo calculation is observed in the MnTe film. This behavior is destroyed by adding Cr in the MnTe film. The temperature dependence of magnetization shows a sharp rise at around 66 K
due to the magneto-elastic coupling. Metallic behavior is observed in the MnTe film in the temperature range 120-220 K
which is ascribed to the magnetic ordering. The metallic behavior disappears with adding Cr
because adding Cr ions destroys the magnetic ordering which is mediated by the sp-d exchange interaction between the Cr ions. 2012 Elsevier B.V.

To improve the fidelity of nanostructures in transfer process
a composite stamp with reasonable hardness distribution in 184 PDMS used to nanoimprint was studied. The stamp is composed of a stiff 184 PDMS structured layer and a soft 184 PDMS supporter layer. We studied the relationship between the hardness of the 184 PDMS and the proportion of each component in 184 PDMS. The appropriate components proportions of prepolymer and curing agent corresponding to the different region of the composite stamp were presented. The fabrication method of the stamp is also presented. Corresponding experiments were carried out by using this stamp. Kinds of nanostructures were transferred in one inch diameter area with good fidelity. The feature sizes of the structures were less than 100 nm. 2012 IEEE.
